Description
The invention relates to novel substituted pyridines and pyrimidines and to fused systems derived therefrom, to processes for their preparation, and to their use as pesticides, in particular as insecticides, acaricides and fungicides. The compounds are furthermore suitable for controlling nematodes, helminths and molluscs, and for controlling endoparasites and ectoparasites in the field of veterinary medicine.
It has already been disclosed that certain 4-alkoxy- and 4-aminopyrimidines show a good fungicidal, acaricidal and insecticidal activity (cf. EP-A-326 328, EP-A-414 368, EP-A-424 125, EP-A-453 137 and EP-A-467 760). However, the biological activity of these compounds is not satisfactory in all areas of application, in particular at low application rates and concentrations.
Novel substituted pyridines and pyrimidines and fused systems derived therefrom have been found, which have the formula I ##STR2## in which the radicals and variables are as defined below.

The present invention relates to the compounds of the formula I in the form of the free base or of an acid addition salt. Acids which can be used to form 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, 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 elements of chirality. Racemates and diastereomers can therefore occur. The invention embraces both the pure isomers and also mixtures of these. The mixtures of diastereomers can be resolved to give the components by customary methods, for example by selective crystallization from suitable solvents or by chromatography. Racemates can be resolved to give the enantiomers by customary methods, for example by forming salts with an optically active acid, resolution 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 ##STR6## 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, for example halogen, alkylthio, alkanesulfonyloxy or arylsulfonyloxy, alkylsulfonyl or arylsulfonyl, with a nucleophile of the formula III ##STR7## in which X, R.sup.4, n, m and Y are as defined under formula I, and, if appropriate, in the event that R.sup.3 is hydrogen and A is nitrogen, the C.sup.5 of the pyrimidine in the resulting compounds of the formula I is chlorinated or brominated.
The substitution reaction described above is known in principle. The leaving group L can be varied within wide limits 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 alkanesulfonyl, such as methylsulfonyl or ethylsulfonyl, or arylsulfonyl such as phenylsulfonyl 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-methylpyrrolidine-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.
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, or organolithium compounds, such as n-butyllithium.
In the event that X is oxygen, then 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, examples of suitable bases are 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. It is also possible to use the second equivalent of an amine III as auxiliary base.
The invention furthermore relates to a process for the preparation of compounds of the formula V which comprises converting a compound of the formula IV ##STR8## in which A, R.sup.1, R.sup.2, R.sup.3, R.sup.4, X, n, m and p are as defined under formula I and
R.sup.8 and R.sup.9 are identical or different and are hydrogen, (C.sub.1 -C.sub.8)-alkyl or (C.sub.1 -C.sub.8)-haloalkyl, or

using an inorganic or organic acid, such as, for example, HCl, H.sub.2 SO.sub.4, HNO.sub.3, H.sub.3 PO.sub.4, oxalic acid, acetic acid or an acidic ion exchanger, into a compound of the formula V ##STR9## in which the radicals A, R.sup.2, R.sup.3, X, R.sup.5, R.sup.6, R.sup.7, m and p are as defined under formula I, Q is HNR.sup.5, HNOR.sup.5, HN-NR.sup.5 R.sup.6 or N(OH)R.sup.5, Ph is an aromatic radical, preferably phenyl, and Z.sup.- is an anion, preferably halide, such as iodide.

In the event that R.sup.2 and R.sup.3 form an unsaturated 5- or 6-membered isocyclic ring which can also contain one or more nitrogen atoms and which is optionally substituted by 1, 2 or 3 identical or different radicals, and these radicals are (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy, (C.sub.1 -C.sub.4)-haloalkyl, (C.sub.1 -C.sub.4)-haloalkoxy and/or halogen, compounds of the formula IV are new and are a subject of the invention.
Compounds of the formula V are starting compounds for the preparation of compounds of the formulae VI and VII, which are prepared by processes analogous to known processes, Z preferably being a halogen atom, in particular Cl, Br or I. The compounds of the formula V are also novel, and are a subject of the invention.
H.sub.2 NOH and compounds of the formula HQ can be employed as the free bases or in the form of their acid addition salts. H.sub.2 NOH or HQ is liberated from the latter in situ by adding a base. Bases which are suitable for this purpose are hydroxides, carbonates, hydrogen carbonates, acetates or alcoholates of alkali metals or alkaline earth metals, such as sodium hydroxide, sodium carbonate, sodium acetate, sodium hydrogen carbonate or potassium carbonate, or organic bases such as triethylamine or pyridine.
The abovementioned reactions which lead to compounds of the formula VI are carried out in a temperature range of -20.degree. to -150.degree. C., and, if appropriate, in an inert organic solvent, such as N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidine-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.
The abovementioned reactions which lead to compounds of the formula VII are carried out in an inert organic solvent or solvent mixture from the series of the abovementioned solvents and solvent mixtures in the presence of a base at a temperature between -80.degree. C. and the boiling point of the reaction mixture, preferably between 10.degree. and 70.degree. C. Examples of suitable bases are hydroxides, alcoholates, carbonates, amides or hydrides of alkali metals or alkaline earth metals, such as sodium hydroxide, sodium ethanolate, sodium carbonate, potassium carbonate, sodium amide or sodium hydride, or organolithium compounds such as n-butyllithium.
The starting compounds of the formula II are either known or can be prepared analogously to known processes; see, for example:
Quinolines: Org. Synth., Coll. Vol. 3, 272 (1955)
1,5-Naphthyridines: J. Amer. Chem. Soc. 68, 1317 (1946) and
British Patent 1147760
1,6-Naphthyridines: J. Chem. Soc. 1960, 1790
1,7-Naphthyridines: J. Org. Chem. 19, 2008 (1954)

Pyridopyrimidines: EP-A-414 386
Pteridines: J. Chem. Soc. 1951, 474
In the event that A is a nitrogen atom, then acetoacetate derivatives, which are converted into the halopyrimidines via the corresponding hydroxypyrimidines, are used as starting materials: ##STR10##
In the event that R.sup.2 and R.sup.3 together with the carbon atoms to which they are bonded form a saturated 5-, 6- or 7-membered isocyclic ring which can contain one or more oxygen or sulfur atoms instead of CH.sub.2 and which is optionally substituted by one to four (C.sub.1 -C.sub.4)-alkyl groups and/or halogen, the compounds of the formula II are novel and are claimed.
The starting compounds of the formula II can furthermore be obtained from malonate derivatives analogously to known processes: ##STR11##
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, for example a complex metal hydride, or alternatively, in the case of an aldehyde or ketone, with hydrogen and a hydrogenation catalyst. Other possibilities are reaction of an organometallic compound with a carbonyl group or an oxirane.
In the event that X is NH, the nucleophiles of the formula III, which are required as starting materials, can also be prepared by known methods, for example by reduction of an oxime 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.
The compounds of the formula I in which R.sup.3 is halogen can be halogenated by known processes.
The compounds of the formula I according to the invention are distinguished by an outstanding fungicidal activity. Fungal pathogens which have already penetrated the plant tissue can successfully be controlled in a curative manner. This is particularly important and advantageous in the case of those fungal diseases which can no longer be controlled effectively with the otherwise customary fungicides once infection has taken place. The spectrum of action of the claimed compounds extends to a range of economically important phytopathogenic fungi but, in particular, to Erysiphe graminis and Leptosphaeria nodorum.
In addition, the compounds according to the invention are also suitable for use in industrial areas, for example as wood preservatives, as preservatives in paints, in cooling lubricants for metalworking, or as preservatives in drilling and cutting oils.
The invention also relates to compositions which contain the compounds of the formula I in addition to suitable formulation auxiliaries. The compositions according to the invention generally contain 1 to 95% of the active substances of the formula I. They can be formulated in various ways, depending on the prevailing biological and/or chemico-physical parameters. Suitable formulations which are possible are therefore the following: wettable powders (WP), emulsifiable concentrates (EC), oil- or water-based aqueous dispersions (SC), suspoemulsions (SC), dusts (DP), seed dressing products, granules in the form of 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 Edition 1986; yon 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 Carrier", 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. Copr., Ridgewood N.J.; Sisley and Wood, "Encyclopaedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte" [Surface-active Ethylene Oxide Adducts], Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Kuchler, "Chemische Technologie" [Chemical Technology], Volume 7, C. Hauser Verlag, Munich, 4th Edition 1986.
Based on these formulations, combinations with other pesticidally active substances, fertilizers and/or growth regulators can also be prepared, for example in the form of readymix or a tankmix.
Wettable powders are preparations which are uniformly dispersible in water and which contain, beside the active substance, wetting agents, for example polyoxethylated alkylphenols, polyoxethylated fatty alcohols, alkylsulfonates or alkylphenolsulfonates, and dispersants, for example sodium ligninsulfonate, sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleylmethyltaurinate, 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 hydrocarbon atoms, with an addition of one or more emulsifiers. Examples of emulsifiers which can be used are:
Calcium alkylarylsulfonate, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers, such as fatty acid polyglycol esters, alkyl aryl polyglycol ethers, fatty alcohol polyglycol ethers, polyoxyethylene-polyoxypropylene eorbitan 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, pyrophillite or diatomaceous earth. Granules can be prepared either by spraying the active substance onto absorptive, granulated inert material or by applying active substance concentrates 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 can also be granulated in the manner customary for the preparation of fertilizer granules, if desired in the form of a mixture with fertilizers.
The active substance concentration in wettable powders is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight is composed of customary formulation auxiliaries. In the case of emulsifiable concentrates, the active substance concentration can be approximately 5 to 80% by weight. Formulations in the form of dusts usually contain 5 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 and the like are being used.
In addition, the abovementioned formulations of active substances contain, 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 also in the case of some microgranules.
Preparations in the form of dusts and granulated preparations and sprayable solutions are conventionally not diluted any further with other inert substances before use.
The application rate required varies with the external conditions, such as temperature, humidity and the like. It can vary within wide limits, for example between 0.005 and 10 kg/ha or more of active ingredient, but it is preferably between 0.01 and 5 kg/ha.

The active substance content of the use forms prepared with the commercially available formulations can be from 0.00000001 up to 95% by weight of active substance, preferably between 0.00001 and 1% by weight.
They are used in a customary manner which suits the use forms.
The active substances according to the invention are also suitable for controlling endoparasites and ectoparasites in the field of veterinary medicine or in the field of animal-keeping.
Here, the active substances according to the invention are administered in a known manner, such as by oral administration in the form of, for example, tablets, capsules, drinks, 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 an injection.
Accordingly, the novel compounds of the formula I according to the invention can also be employed particularly advantageously in livestock breeding (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 to the animals orally, if appropriate together with the drinking water or feed. Since they are excreted highly effectively with the feces, this allows the development of insects in the feces of the animals to be prevented in a very simple manner. The dosage rates and formulations which are suitable in each case will depend, in particular, on the species and the development stage of the livestock and also on the severity of the infection, and they can be determined and decided easily by customary methods. In the case of cattle, for example, the novel compounds can be employed at dosage rates from 0.01 to 1 mg/kg of bodyweight.
The examples which follow are intended to illustrate the invention without restricting it thereto.
