Description
The present invention relates to novel condensed heterocyclic derivatives, a process for their production and selective herbicides containing such derivatives as active ingredients, which are useful particularly as herbicides for paddy field and upland field.
Heretofore, a number of herbicides have been practically used to protect important crop plants such as rice, soybean, peanut, sunflower, sorgo, wheat, corn, cotton and sugar beet from weeds and to increase the productivity of such important crop plants. In recent years, with a worldwide increase of population, it is evident that the productivity of such important crop plants gives a direct influence over the food economy of the world. From this viewpoint, it is increasingly important for those concerned with agriculture to develop herbicides which are capable of efficiently controlling weeds which hinder the cultivation of such important crop plants.
As such herbicides, it is desired to develop active agents which satisfy the following conditions.
They should have proper residual activities. (In recent years, there has been a problem that active agents having long residual life in soil give damages to the subsequently cultivated plants, and it is important that the residual activities after application should be proper). After the application, they should quickly kill weeds. (It is especially effective to control concurrently germinating weeds at the initial growing stage of crop plants to improve the subsequent growing conditions of the crop plants). The number of applications should be small. (This is important also with a view to saving the labor for the weed controlling operation.) In a cultivated field where crop plants and weeds are concurrently present, they should selectively kill only the weeds by the simultaneous foilage treatment of both the crop plants and the weeds. (Reflecting the trend for non-plowing cultivation, there is an increasing trend for foilage treatment during the growing stage rather than the conventional soil incorporation.) They should not adversely affect the crop yield. (It is important that they do not create an adverse effect to the yield such as the growth control, at the time of the hervesting.) They should be effective against perennial weeds. (Major weeds of the world include many perennial weeds.) They should have high herbicidal effects at a low dose. (Especially from the viewpoint of the environmental protection, it is desired to kill weeds at a low dose of the active agent.)
However, conventional herbicides do not necessarily satisfy all of the above conditions.
On the other hand, it is already known that certain condensed heterocyclic compounds exhibit herbicidal activities. For example, in the Pesticide Manual, 8th edition, p 670, by The British Crop Protection Council (1987), Benazolin is disclosed as a herbicide having a condensed heterocyclic structure. However, such a compound is inadequate in the herbicidal effects or plant selectivity and can not necessarily be regarded as being suitable as a herbicide for paddy field or upland field.
Further, Japanese Unexamined Patent Publication No. 91/1987 disclosed a compound having the following formula: ##STR3## Such a compound exhibits herbicidal effects even at a low dose. However, the selectivity range between crop plants and weeds in the foilage treatment is narrow, and it is inadequate as a herbicide for upland field.
Under these circumstances, the present inventors have conducted extensive research to develop a herbicide having selectivity for important crop plants and showing excellent herbicidal effects at a low dose. As a result, they have found that condensed heterocyclic derivatives of the formula I given below (hereinafter referred to as the compounds of the present invention) exhibit high herbicidal activities as upland herbicides in both soil and foilage treatments against broad-leaved weeds including Solanaceae weeds such as Solanum nigrum and Datura stramonium, Malvaceae weeds such as Abutilon theophrasti or Sida spinosa, Convolvulaceae weeds such as Ipomoea spps. including Ipomoea purpurea, or Calystegia spps., Amaranthaceae weeds such as Amaranthus lividus or Amaranthus retroflexus, Compositae weeds such as Xanthium pensylvanicum, Ambrosia artemisiaefolia, Helianthus annus, Galinsoga ciliata, Cirsium arvense, Senecio vulgaris or Erigeron annus, Cruciferae weeds such as Rorippa indicia, Sinapis arevnsis or Capsella Bursapastoris, Polygonaceae weeds such as Polygonum Blumei or Polygonum convolvulus, Portulacaceae weeds such as Portulaca oleracea, Chenopodiaceae weeds such as Chenopodium album, Chenopodium ficifolium or Kochia scoparia, Caryophyllaceae weeds such as Stellaria media, Scrophulariaceae weeds such as Veronica persica, Commelinaceae weeds such as Commelina communis, Labiatae weeds such as Lamium amplexicaule or Lamium purpureum, Euphorbiaceae weeds such as Euphorbia supina or Euphorbia maculata, Rubiaceae weeds such as Galium spurium or Rubia akane, Violaceae weeds such as Viola mandshurica, Leguminosae weeds such as Sesbania exaltata or Cassia obtusifolia and against various upland weeds including graminaceous weeds such as Sorgham bicolor, Panicum dichotomiflorum, Sorghum halepense, Echinochloa crus-galli, Digitaria adscendens, Avena fatua, Eleusine indicia, Setaria viridis or Alopecurus aegualis, and Cyperaceous weeds such as Cyperus rotundus or Cyperus esculentus, and they also exhibit high herbicidal activities as paddy field herbicides at a low dose in both irrigated soil treatment and foilage treatment against paddy weeds including Alismataceae weeds such as Alisma canaliculatum, Sagittaria trifolia or Sagittaria pygmaea, Cyperaceae weeds such as Cyperus difformis, Cyperus serotinus, Scirpus juncoides or Eleocharic kuroguwai, Scrothulariaceae weeds such as Lindemia pyxidaria, Potenderiaceae weeds such as Monochoria vaginalis, Potamogetonaceae weeds such as Potamogeton distinctus, Lythraceae weeds such as Rotala indica, and Gramineae weeds such as Echinochloa crus-galli. Further, it has been found that the compounds of the present invention are highly safe against important crop plants such as rice, wheat, barely, sorgo, peanut, corn, soybean, cotton and sugar beet.
The present invention has been accomplished on the basis of these discoveries.

The present invention also provides a process for producing the condensed heterocyclic derivative of the formula I which comprises reacting a thiosemicarbazone derivative of the formula: ##STR10## wherein Z is as defined in claim 1, with a compound of the formula: ##STR11## wherein X is as defined in claim 1.
Further, the present invention provides a herbicide which comprises a herbicidally effective amount of the condensed heterocyclic derivative of the formula I and an agricultural carrier or diluent.
It is a feature of the present invention that the compounds of the present invention include those having a wide range of selectivity in the foilage treatment of the crop plants and weeds, particularly in the selectivity between soybean and weeds, or peanut and weeds, as compared with the conventional compounds, and they have highly safe against such crop plants.
Further, among these compounds, some exhibit high safety against corn, or some exhibits high safety against rice.
On the other hand, the compounds of the present invention exhibit high herbicidal effects promptly at a low dose as compared with the conventional herbicides. Therefore, some of the compounds are useful also as herbicides for orchards, grasslands, lawns or non-agricultural fields.
The compounds of the present invention represented by the formula I are novel compounds.
Heretofore, Hans Kefer, disclosed in Synthesis, 81 (1972) that in the synthesis of an N-acyllactam, an enamide is obtainable by acylation in the presence of a base: ##STR12##
Further, Wolfgang Oppolzer, et al. disclose in Tetrahedron Letters, 981, (1979), a process for synthesizing a dienamide by acylating an imine derivative: ##STR13##
However, as in the case of the compounds of the present invention, a process for cyclizing and synthesizing an enamide structure by acylating a thiosemicarbazone derivative i.e. a novel compound of the formula II, has not been known and is a novel process.
Now, the process for the production of the compounds of the present invention will be described in detail.
The compound of the present invention represented by the formula I can readily be prepared by reacting a thiosemicarbazone derivative of the formula II with from 1.0 to 2.0 equivalent of a compound of the formula III in a solvent in the presence of from 2.0 to 4.0 equivalent of a base at a temperature of from 0.degree. to 200.degree. C., for example, at 20.degree. C. or at a reflux temperature for from 30 minutes to 48 hours.
The solvent may be an aliphatic hydrocarbon such as hexane, heptane, ligroin or petroleum ether, an aromatic hydrocarbon such as benzene, toluene or xylene, a halogenated hydrocarbon such as chloroform, methylene chloride or chlorobenzene, an ether such as diethyl ether, dioxane, ethylene glycol dimethyl ether or THF, a ketone such as acetone or methyl ethyl ketone, a nitrile such as acetonitrile or isobutyronitrile, a tertiary amine such as pyridine or N,N-diethylaniline, an acid amide such as formamide or N,N-dimethylformamide, a sulfur compound such as dimethyl sulfoxide or sulforane, or a mixture thereof.
The base may be an organic base such as pyridine, triethylamine, 1,4-diazabicycle[2.2.2]octane or N,N-diethylaniline, or an inorganic base such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate or sodium hydride.
When the compound of the formula III is phosgene i.e. X in the formula III being an oxygen atom, phosgene per ce may be used for the reaction. However, a so-called phosgene dimer i.e. ClCO.sub.2 CCl.sub.3 (trichloromethyl chloroformate) may be used so that it acts as phosgene in the reaction system.
After completion of the reaction, the solvent is distilled off to some extent, and then the solution is poured into water to obtain crude crystals. Otherwise, after an addition of water, the reaction solution is extracted with an organic solvent, and the extract is washed, if necessary, with a dilute alkaline aqueous solution, a dilute acidic aqueous solution or water and then subjected to usual aftertreatment such as drying or concentration to obtain a crude product.
The crude product may then be subjected to purification such as recrystallization, column chromatography, fractional liquid chromatography or fractional thin layer chromatography to obtain the desired compound of the present invention.
The compound of the present invention can be obtained by the synthesis route represented by Scheme (1) which includes the above process. ##STR14##
In Scheme (1), Z and X are defined above, and R' is a usual leaving group such as a lower alkyl group, a substituted benzyl group or CH.sub.2 CO.sub.2 H.
The starting compound 1,4,5,6-tetrahydropyridazine (a) can be prepared by the methods disclosed in e.g. Heyns Kurt, et al., Chem. Ber., 109 (11), 3707 (1976), N. Viswanathan, A. R. Sidhays, Tetrahedron Lett., 52, 5025, (1979), and David L. Klopotek, et al., J. Org. Chem., 45 (9), 1665 (1980) or similar methods, or by entirely new methods as shown by Schemes (2) to (4). ##STR15##
The step of g.fwdarw.a in Scheme (2), the steps of k.fwdarw.l and l.fwdarw.a in Scheme (3) and the step of m.fwdarw.a in Scheme (4) are novel processes. In scheme (2), R" is a lower alkyl group.
The starting materials and reagents used in the above methods are either known or can be prepared by the above-mentioned methods or other methods similar to such known methods.
Now, the syntheses of the compounds of the present invention and their intermediates will be described in detail as Examples and Reference Examples. However, it should be understood that the present invention is by no means restricted to such specific Examples.

The soil was covered thereon in the thickness of about 1 cm, and then a herbicide solution was applied onto the surface of the soil uniformly so that the active ingredient was distributed at a predetermined concentration. The herbicide solution was prepared by diluting the wettable powder, the emulsifiable concentrate, the dry flowable or the flowable as described in the foregoing Formulation Examples with water and applied onto the entire soil surface by means of a small spray.
Three weeks after the application of the herbicidal solution, the herbicidal effects against each weed and Zea mays and Glycine max were determined on the basis of the following standard ratings. The results thereby obtained are shown in Table 3. Some of the compounds of the present invention have selectively for certain crop plants.
Standard ratings
5: Growth control rate of more than 90% (almost completely withered)
4: Growth control rate of from 70 to 90%
3: Growth control rate of from 40 to 70%
2: Growth control rate of from 20 to 40%
1: Growth control rate of from 5 to 20%
0: Growth control rate of less than 5% (almost non-effective)
The above growth control rates were calculated by the following equation: ##EQU1## where
T: Weight of the weed growth above the soil surface of the treated area
N: Weight of the weed grown above the soil surface of the non-treated area
TEST EXAMPLE 2: TEST ON THE HERBICIDAL EFFECTS IN FOLIAGE TREATMENT

Then, the soil was covered thereon in a thickness of about 1 cm. When the various plants grew to the 2 or 3 leaf stage, a herbicidal solution was uniformly sprayed on the foliages so that the active ingredient was applied in a predetermined concentration.
The herbicidal solution was prepared by diluting the wettable powder, the emulsifiable concentrate, the dry flowable or the flowable as described in the above Formulation Examples with water and applied onto the entire surface of the foliages of the weeds and the crop plants by a small spray. Four weeks after the application of the herbicide solution, the herbicidal effects against each weed were determined on the basis of the standard ratings described in Test Example 1. The results are shown in Table 4.
TEST EXAMPLE 3: TEST ON THE HERBICIDAL EFFECTS IN AN IRRIGATED CONDITION
A 1/5,000 are Wagner pot was filled with alluvial soil. Water was introduced and mixed to form an irrigated condition with water depth of 2 cm. Seeds of Echinochloa oryzicola, Monochoria vaginalis, Rotala indica and Scirpus juncoides were sown, and tubers of Sagittaria pygmaea were planted. Further, rice seedlings of 2.5 leaf stage were transplanted. Then, the pot was kept in a green house at a temperature of from 25.degree. to 30.degree. C. for the cultivation of the plants. Three days later, a diluted herbicidal solution was dropwise applied to the water surface in a predetermined dose by a measuring pipette. Three weeks after the dropwise application of the herbicide, the herbicidal effects against various weeds and rice were determined on the basis of the standard ratings described in Test Example 1. The results are shown in Table 5.
