Description
The invention relates to novel substituted spiroalkylamino and -alkoxy nitrogen heterocycles, to processes for their preparation, and to their use as pesticides and fungicides.

The present invention relates to the compounds of the formula I in the form of the free base or in the form of an acid addition salt. Acids which can be used for the formation of salts are inorganic acids, such as hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid, phosphoric acid, or organic acids, such as formic acid, acetic acid, propionic acid, malonic acid, oxalic acid, fumaric acid, adipic acid, stearic acid, oleic acid, methanesulfonic acid, benzenesulfonic acid or toluenesulfonic acid.
Some of the compounds of the formula I have one or more asymmetric carbon atoms or stereoisomers on double bonds. Enantiomers or diaestereomers may therefore occur. The invention embraces the pure isomers and also their mixtures. The mixtures of diastereomers can be separated into the components by customary methods, for example by selective crystallization from suitable solvents or by chromatography. Racemates can be resolved into the enantiomers by customary methods, for example by salt formation using an optically active acid, separation of the diastereomeric salts and liberation of the pure enantiomers by means of a base.
The invention furthermore relates to a process for the preparation of compounds of the formula I which comprises reacting a compound of the formula II ##STR5## in which A, R.sup.1, R.sup.2 and R.sup.3 are as defined under formula I and L is a leaving group such as, for example, halogen, alkylthio, alkanesulfonyloxy or arylsulfonyloxy, alkylsulfonyl or arylsulfonyl, with a nucleophile of the formula III ##STR6## in which a, b, r, s, E, U, V, W, X, Y, Z, R.sup.4, R.sup.5 and R.sup.6 are as defined above under formula I, and optionally subjecting the compounds of the formula I which have been obtained in this or a different manner to further derivatization on the heterocycle and/or in the side chain R.sup.6 and, if appropriate, converting the compounds into their salts.
The above-described substitution reaction is known in principle. The leaving group Z can be varied within a wide range and can be, for example, a halogen atom, such as fluorine, chlorine, bromine or iodine; or alkylthio, such as methylthio or ethylthio; or alkanesulfonyloxy, such as methane-, trifluoromethane- or ethanesulfonyloxy; or arylsulfonyloxy, such as benzenesulfonyloxy; or toluenesulfonyloxy, or alkylsulfonyl, such as methyl- or ethylsulfonyl; or arylsulfonyl, such as phenyl- or toluenesulfonyl.
The abovementioned reaction is carried out in a temperature range of 20.degree.-150.degree. C., expediently in the presence of a base and, if appropriate, in an inert organic solvent, such as N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidin-2-one, dioxane, tetrahydrofuran, 4-methyl-2-pentanone, methanol, ethanol, butanol, ethylene glycol, ethylene glycol dimethyl ether, toluene, chlorobenzene or xylene. Mixtures of the abovementioned solvents can also be used.
In the event that X is oxygen or S(O).sub.x, examples of suitable bases are the carbonates, hydrogen carbonates, amides or hydrides of alkali metals or alkaline earth metals, such as sodium carbonate, sodium hydrogen carbonate, potassium carbonate, sodium amide or sodium hydride, in the event that X is NH, suitable bases are, for example, the carbonates, hydrogen carbonates, hydroxides, amides or hydrides of alkali metals or alkaline earth metals, such as sodium carbonate, sodium hydrogen carbonate, potassium carbonate, sodium hydroxide, sodium amide or sodium hydride, or organic bases, such as triethylamine or pyridine, or else a second equivalent of the nucleophile where X=NH.
The invention furthermore relates to a process for the preparation of compounds of the formula I in which Y and Z are oxygen and W is a group (CH.sub.2).sub.n in which n is 2, 3 or 4, which comprises reacting, in the presence of an acidic catalyst, a compound of the formula IV ##STR7## in which a, b, r, A, X, E, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined above for formula I, with a diol of the formula V ##STR8## in which U, V, R.sup.5, R.sup.6 and s are as defined above and n is a number 2, 3 or 4, to give, with the elimination of water, the compounds of the formula I and, if appropriate, subjecting these compounds to further derivatization in the side chain R.sup.6.
The above-described ketalization reaction is known in principle. It is carried out in a temperature range of 20.degree.-200.degree., preferably between 60.degree. and 150.degree. in the presence of an acidic dehydration catalyst, in substance or in an inert solvent. Examples of suitable catalysts are hydrochloric acid, sulfuric acid, phosphoric acid, sodium hydrogen sulfate, sulfonic acid, such as methane- or toluenesulfonic acid, phosphorus (V) oxide, iron (III) chloride, zinc chloride, anhydrous copper sulfate, iodine or else acidic ion exchangers, such as, for example, .RTM.Amberlite IR-120. The water formed during the reaction is expediently removed by distillation, if appropriate under reduced pressure, or by azeotropic distillation using an entrainer. Examples of suitable entrainers are benzene, toluene, xylene or petroleum ether.
The invention furthermore relates to a process for the preparation of compounds of the formula I in which Y and Z are oxygen and W is a group (CH.sub.2).sub.n in which n is 2, 3 or 4, which comprises reacting, in the presence of an acidic catalyst, a compound of the formula I' ##STR9## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, a, b, r, s, A, X and E are as defined for formula I, n is 2, 3 or 4 and s is 0, with a diol of the formula V, to obtain the end products with ketal exchange. The reaction temperature, the solvent and the catalysts correspond to those which have been described in the reaction of the compounds of the formula IV with the compounds of the formula V. The diol V is expediently employed in an excess.
In the event that X is oxygen, the nucleophiles of the formula III, which are required as starting materials, can be prepared by known processes, for example by reducing a carbonyl group with a suitable reducing agent, such as a complex metal hydride, or, in the case of an aldehyde or ketone, also using, for example, hydrogen and a hydrogenation catalyst. Other possibilities are the reaction of an organometallic compound with a carbonyl group or with an oxirane.
In the event that X is NH, the nucleophiles of the formula III, which are required as starting materials, can be prepared by known methods, for example by reducing an oxime or a nitrile with a suitable reducing agent, for example a complex metal hydride or hydrogen in the presence of a hydrogenation catalyst, reductive amination or Leuckart-Wallach reaction of an aldehyde or ketone, or Gabriel reaction of an alkyl halide or alkyl tosylate.
Those nucleophiles of the formula III which are used as precursors for the preferred compounds of the formula I in which E is a direct bond are obtained from the corresponding cycloalkanones of the formula VI ##STR10## in which a, b, r, s, U, V, W, Y, Z, R.sup.4, R.sup.5 and R.sup.6 are as defined above for formula I, as described above, for example by means of reductive amination or reduction with a complex hydride.
Depending on a, b, r, s, W, Y and Z, these compounds of the formula VI can be prepared by reactions known in principle.
For example, Spiro derivatives of cyclohexanone
(a.dbd.b.dbd.2) can be obtained by the following methods:
a) Y.dbd.Z.dbd.CH.sub.2 ; W=direct bond (cyclopropane derivatives) ##STR11## R (here and hereinbelow)=organic radical b) Y.dbd.Z.dbd.CH.sub.2 (cyclobutane derivatives) ##STR12## c) Y.dbd.O, Z.dbd.CH.sub.2 ; W.dbd.CH.sub.2 (oxetane derivatives) ##STR13## Nu e.g.=HOR, HSR R=alkyl, aryl, etc. Synthesis 1988, 862 3) Y.dbd.Z.dbd.CH.sub.2 ; W.dbd.(CH.sub.2).sub.n (spiroalkanes) ##STR14## e) Y.dbd.CH.sub.2 ; Z.dbd.O; W.dbd.(CH.sub.2).sub.n (oxa-spiroalkanes) ##STR15## f) Y.dbd.Z.dbd.O; W.dbd.(CH.sub.2).sub.n ; (ketals) ##STR16##
The reactions described under a), b), c) and e) can also be carried out using cyclohexane-1,4-dione as the precursor, albeit with poorer yields.
Suitable precursor which have rings of different sizes (a, b.noteq.2) have also been described (Tetrahedron Lett. 28 (1987) 551).
All reactions starting from cyclohexane-1,4-dione monoketal (VII) can also be carried out with the 4-ketocyclohexylamine derivative IV'. ##STR17##
Epoxide derivatives (X.dbd.CH.sub.2, Z.dbd.O, W=direct bond between Y and Z) are best prepared from the ketones IV or the exo-alkylene derivatives XII. ##STR18##
The preparation of the precursors of the formulae IV and XII is described in DE-A-43 31 179.

The invention also relates to compositions, in particular insecticidal, nematocidal and acaricidal compositions, which comprise the compounds of the formula I as well as suitable formulation auxiliaries.
The active substances of the formulae I generally amount to 1 to 95% by weight of the compositions according to the invention.
They can be formulated in various ways, depending on the biological and/or chemico-physical parameters. Possible formulations which are suitable are therefore: wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions, sprayable solutions, oil- or water-based dispersions (SC), suspoemulsions (SE), dusts (DP), seed-dressing products, granules in the form of microgranules, spray granules, coated granules and adsorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits.
These individual types of formulations are known in principle and are described, for example, in: Winnacker-Kuchler, "Chemische Technologie" Chemical Technology!, Volume 7, C. Hauser Verlag Munich, 4th Ed. 1986; van Falkenberg, "Pesticides Formulations", Marcel Dekker N.Y., 2nd Ed. 1972-73; K. Martens, "Spray Drying Handbook", 3rd Ed. 1979, G. Goodwin Ltd. London.
The formulation auxiliaries required, such as inert materials, surfactants, solvents and other additives are also known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Darland Books, Caldwell N.J.; H. v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd Ed., J. Wiley & Sons, N.Y.; Marschen, "Solvents Guide", 2nd Ed., Interscience, N.Y. 1950; McCutcheon's, "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte" Surface-active Ethylene Oxide Adducts!, Wiss. Verlagsgesell., Stuttgart 1967; Winnacker-Kuchler, "Chemische Technologie", Volume 7, C. Hauser Verlag Munich, 4th Ed. 1986.
Based on these formulations, it is also possible to prepare combinations with other pesticidally active substances, fertilizers and/or growth regulators, for example in the form of a readymix or a tank mix. Wettable powders are preparations which are uniformly dispersible in water and which, besides the active substance, also comprise wetting agents, for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, alkyl sulfonates or alkylphaenol sulfonates, and dispersants, for example sodium lignosulfonate or sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, in addition to a diluent or inert substance.
Emulsifiable concentrates are prepared by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or else higher-boiling aromatics or hydrocarbons, with the addition of one or more emulsifiers. Examples of emulsifiers which can be used are: calcium alkylarylsulfonates, such as calcium dodlecylbenzenesulfonate, or non-ionic emulsifiers, such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters.
Dusts are obtained by grinding the active substance with finely divided solid substances, for example talc, natural clays, such as kaolin, bentonite or pyrophyllite, or diatomaceous earth. Granules can be prepared either by spraying the active substance onto adsorptive granulated inert material or by applying concentrates of active substance to the surface of carriers such as sand, kaolinites or granulated inert material with the aid of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Suitable active substances may also be granulated in the manner which is customary for the preparation of fertilizer granules, if desired in the form of a mixture with fertilizers.
The concentration of active substance in wettable powders is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the concentration of active substance may amount to approximately 5 to 80% by weight. Formulations in the form of dusts comprise in most cases 5 to 20% by weight of active substance, sprayable solutions approximately 2 to 20% by weight. In the case of granules, the active substance content depends partly on whether the active compound is in liquid or solid form and on which granulation auxiliaries, fillers etc. are being used.
In addition, the abovementioned formulations of active substances comprise, if appropriate, the adhesives, wetting agents, dispersants, emulsifiers, penetrants, solvents, fillers or carriers which are customary in each case.
For use, the concentrates, which are in commercially available form, are, if appropriate, diluted in the customary manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and some microgranules. Preparations in the form of dusts or granules and sprayable solutions are conventionally not diluted any further with other inert substances before being used.
The application rate required varies with the external conditions, such as, inter alia, temperature and humidity. It can vary within wide limits, for example between 0.0005 and 10.0 kg/ha or more of active substance, but it is preferably between 0.001 and 5 kg/ha.
The active substances according to the invention may be present in the commercially available formulations and in the use forms prepared with these formulations in the form of mixtures with other active substances, such as insecticides, attractants, sterilants, acaricides, nematicides, fungicides, growth-regulating substances or herbicides.

The active substance content of the use forms prepared from the commerically available formulations can range from 0.00000001 to 95% by weight of active substance and is preferably between 0.00001 and 1% by weight.
They are applied in a conventional manner adapted to suit the use forms.
The active substances according to the invention are also suitable for controlling endo- and ectoparasites in the field of veterinary medicine or the field of animal husbandry.
The active substances according to the invention are administered in a known manner, for example by oral administration in the form of, for example, tablets, capsules, potions or granules, by dermal administration, for example in the form of dipping, spraying, pouring-on and spotting on and dusting, and by parenteral administration, for example in the form of injection.
Accordingly, the novel compounds of the formula I according to the invention can also be applied particularly advantageously in livestock husbandry (for example cattle, sheep, pigs and poultry such as chickens, geese and the like). In a preferred embodiment of the invention, the novel compounds, if appropriate in suitable formulations (cf. above) are administered orally to the animals, if appropriate together with the drinking water or the feed. Since the compounds are excreted effectively with the feces, the development of insects in the feces of the animals can be prevented very simply. The dosages and formulations which are suitable in each case depend, in particular, on the species and development stage of the livestock and also on the risk of infection and can readily be determined and fixed by customary methods. In the case of cattle, for example, the novel compounds can be employed in dosages of 0.01 to 1 mg/kg of body weight.
The compounds of the formula I according to the invention are also distinguished by an outstanding fungicidal activity. Fungal pathogens which have already penetrated the plant tissue can successively be controlled curatively. This is particularly important and advantageous in the case of those fungal diseases which can no longer be controlled effectively with the other customary fungicides when infection has taken place already. The spectrum of action of the claimed compounds embraces various economically important phytopathogenic fungi such as, for example, Plasmopara viticola, Erysiphe graminis and Puccinia recondita.
In addition, the compounds according to the invention are also suitable for use in technical fields, for example as wood preservatives, as preservatives in paints, in cooling lubricants for metalworking, or as preservatives in drilling and cutting oils.
The active substances according to the invention in their commercially available formulations can either be employed on their own or in combination with other fungicides known from the literature.

The abovementioned components for combinations are known active substances, many of which are described in Ch.R Worthing, S. B. Walker, The Pesticide Manual, 7th Edition (1983), British Crop Protection Council. The active substance content of the use forms prepared from the commercially available formulations can vary within wide limits, and the concentration of active substance in the use forms can range from 0.0001 to 95% by weight of active substance and is preferably between 0.0001 and 1% by weight.

B. BIOLOGICAL EXAMPLES
Fungicidal Action
Example 1
Puccinia recondita
Wheat cv. "Jubilar" in the 2-leaf stage is treated to runoff point with aqueous suspensions of the claimed compounds.
After the spray coating has dried on, plants are inoculated with an aqueous spore suspension of Puccinia recondita. The dripping wet plants are placed in a controlled-environment cabinet at 20.degree. C. and a relative atmospheric humidity of approximately 100% for approximately 15 hours. They are subsequently grown on in a greenhouse at a temperature of 22.degree.-25.degree. C. and a relative atmospheric humidity of 50-70%.
After an incubation time of approximately 2 weeks, the fungus sporulates on the entire leaf surface area of the untreated control plants (100% infection), so that the disease level of the test plants can be evaluated. The disease level is expressed in % diseased leaf area in comparison to the untreated, infected control plants.
At a rate of 500 mg/l of spray mixture, disease is suppressed completely by the following Example numbers: 503, 530, 539, 546, 803, 804, 815, 853.

The reaction solution was then allowed to cool to approximately 35.degree. C., and 1.60 g (8.9 mmol) of 4,5-dichloro-6-ethylpyrimidine dissolved in 3 ml of dry THF were added rapidly, and the reaction mixture was refluxed until the reaction was complete (approximately 2 hours, TLC check). After the reaction mixture had cooled to room temperature, 3 ml of isopropanol were added to destroy excess sodium hydride, the mixture was stirred for a further 15 minutes and poured into a mixture of in each case 100 ml of ether and saturated aqueous ammonium chloride solution. The aqueous phase was extracted thoroughly using ether, and the combined organic phases were dried over magnesium sulfate and subsequently concentrated in vacuo.

To complete the reaction, the mixture was heated at 40.degree. C. for a further 15 hours. To destroy excess sodium borohydride, approximately 5 ml of acetone were added to the reaction solution and stirring was continued at 40.degree. C. for a further 30 minutes. The reaction solution was subsequently concentrated in vacuo and the product taken up in ether and washed using ammonium chloride solution and water. The organic phase was dried carefully over magnesium sulfate and subsequently evaporated to dryness. This gave 11.8 g (90.0%) of the desired cyclohexanol. The crude product was further reacted without further purification.
