Substituted pyridines, their preparation, and their use as pesticides and fungicides

The invention relates to novel substituted 4-amino- and 4-hydroxypyridines, to processes for their preparation, and to their use as pesticides, in particular as insecticides, acaricides and fungicides.
It has already been disclosed that certain substituted 4-amino- and 4-hydroxypyridines have a fungicidal, acaricidal and insecticidal activity (cf. WO 93/05050). However, the biological activity of these compounds is not satisfactory in all fields of application, in particular when low application rates and concentrations are used.
Novel substituted 4-amino- and 4-hydroxypyridines of the formula 1, which are biologically active, have now been found. ##STR2##

Acids which can be used for salt formation 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 1 have one or more asymmetric carbon atoms. Racemates and diastereomers can therefore occur. The invention embraces the pure isomers as well as 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 by customary methods to give the enantiomers, for example by salt formation 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 1 which comprises reacting compounds of the formula 2 ##STR5## in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined above and L is a leaving group, with suitable amines, alcohols, phenols or mercaptans, or, for forming compounds of the formula 1 in which Z is as defined under (5b), hydrogenating those compounds of the formula 1 in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, X and Y are as defined above and Z is an unsaturated carbocyclic radical which is substituted as defined for cycloalkyl or cycloalkenyl under (5b), preferably a phenyl radical which is substituted this way, and, if appropriate, converting the resulting compounds of the formula 1 into a salt thereof.
The above-described substitution reaction is known in principle. The leaving group 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 methanesulfonyloxy, trifluoromethanesulfonyloxy or ethanesulfonyloxy, or arylsulfonyloxy, such as benzenesulfonyloxy or toluenesulfonyloxy, or alkylsulfonyl, such as methylsulfonyl or ethylsulfonyl, or arylsulfonyl, such as phenylsulfonyl or toluenesulfonyl.
The compounds of the formula 2 can be prepared by known methods [for example J.Med., Chem. 32, 1970 (1989), J. Org. Chem. .29 776 (1964), J. Prakt. Chem. 331, 369 (1989), J. Org. Chem. 14, 97 (1949), Chem. Ber. 74, 11111 (1941)]. Preferred compounds 2 which are used for the preparation of the compounds 1 are those in which L=Cl.
The reactions with alcohols and mercaptans are carried out in the presence of a strong base, such as sodium hydride, potassium hydride or potassium tert-butylate, in an inert aprotic solvent, such as DMF, NMP, DMSO, THF, dioxane or sulfolane, at a temperature between 0.degree. and 80.degree. C.; if alcoholates are reacted, it may also be advantageous to use the corresponding alcohol as a solvent.
The conditions for the reactions of 2 with amines depend on the substituents R.sub.1 to R.sub.4 in 2 and on the structure of the amines employed; if the radicals R.sub.1 to R.sub.4 in 2 are inert, 2 can be reacted with an excess of amine with or without solvent at temperatures between 80.degree. and 200.degree. C. to give 1. The excess of amine can be reduced and the temperature can be lowered if acidic catalysts, such as phenol [J. Amer. Chem. Soc. 73, 2623 (1951)] or salts, such as triethylammonium chloride or ammonium chloride, are used. Examples of suitable solvents are DMF, N,N-dimethylacetamide, DMSO, NMP, dioxane, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, sulfolane, toluene, chlorobenzene or xylene. Mixtures of the abovementioned solvents can also be used.
If one or more radicals of R.sup.1 to R.sup.4 in 2 are an RO function, then amines give poor yields of 1 or other undesired reaction products when using the abovementioned methods; exceptions are the reactions with anilines and O-alkyl- or O-aralkyl-hydroxylamines, which give the products 3 and 4 (R' is a substituent of the phenyl). ##STR6##
The compounds of the formula 3 can be hydrogenated catalytically by known methods [for example F. Zymalkowski, Katalytische Hydrierungen [Catalytic Hydrogenation Reactions], p. 191, Enke Verlag, Stuttgart 1965] to give compounds of the formula 1 (Diagram 1). ##STR7##
The resulting cis/trans mixtures can be separated by crystallization or chromatography.
The compounds of the formula 4 are suitable intermediates for preparing a broad range of compounds of the formula 1 in which X.dbd.NH (Diagram 2) ##STR8##
At level 1, the products of formula 4 are reacted selectively on the nitrogen substituent in the 4-position of the pyridine ring with alkylating agents of the formula L--Y--Z in the presence of bases, such as sodium hydride or potassium tert-butylate, to give 5; in formula L--Y--Z, L is halogen or R--SO.sub.3, Y is as defined above (with the exception of aryl) and Z is as above. If sterically uniform alkylating agents are used it is also possible to obtain sterically uniform reaction products in this manner. Solvents which are employed in this reaction are, for example, DMF, DMSO, THF, dimethoxyethane, dioxane, diethylene glycol dimethyl ether, sulfolane or toluene. Mixtures of the abovementioned solvents can also be used. At level 2, the compounds of formula 5 are converted reduetively to the compounds of the formula 1 using known methods [R. Huisgen et al. B. 101, 2559 (1968) C. H. Rayburn, W. R. Harlau, H. R. Haumer Am. Soc. 72, 1721 (1950)].
The amines, alcohols and alkylating agents employed are accessible by methods known from the literature.
The alcohols can be prepared, for example, by reducing a carbonyl group with a suitable reducing agent, for example a complex metal hydride or, in the case of an aldehyde or ketone, also with hydrogen and a hydrogenation catalyst. Other possibilities are the reaction of an organometal compound with a carbonyl group or an oxirane. To synthesize cyclohexanol derivatives, suitable substituted phenols can also be reacted with hydrogen in the presence of a hydrogenation catalyst.
The amines can be prepared, for example, by reduction of 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. To synthesize cyclohexylamine derivatives, suitable substituted anilines can also be reacted with hydrogen in the presence of a hydrogenation catalyst.
The compounds of the formula 1 according to the invention are distinguished by an outstanding fungicidal activity. Fungal pathogens which have already penetrated the plant tissue can be controlled successfully 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 embraces a range of economically important phytopathogenic fungi, such as, for example, Phytophthora infestans, Plasmopara viticola, but also Erysiphe graminis and Pyrenophora teres.
The compounds according to the invention are also suitable for use in industrial fields, for example as a wood preservative, a preservative, in sealants, 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 1 in addition to suitable formulation auxiliaries. The compositions according to the invention generally contain 1 to 95% by weight of the active substances of the formula 1.
They can be formulated in different ways, depending on the prevailing biological and/or chemical-physical parameters. The following are therefore suitable as possible formulations: wettable powders (WP), emulsifiable concentrates (EC), aqueous dispersions on an oil or water base (SC), suspoemulsions (SC), dusts (DP), seed-dressing agents, granules in the form of water-dispersible granules (WG), ULV formulations, micro-capsules, waxes or baits.
These individual types of formulation 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; van Falkenherg, "Pesticides Formulations", Marcel Dekker N.Y., 2nd Ed. 1972 to 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 equally known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carrier", 2nd Ed., Darland Books, Caldwell New Jersey; H. V. Olphen, "Introduction to Clay Colloid Chemistry", 2nd Ed., J. Wiley & Sons, New York ; Marschen, "Solvents Guide", 2nd Ed., Interscience, New York 1950; McCutcheon's "Detergents and Emulsifiers Annual", MG Publ. Corp., Ridgewood New York ; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., New York 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte [Surface-Active Ethylene Oxide Adducts]", Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Kechler, "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 a ready mix or a tank mix.
Wettable powders are preparations which are uniformly dispersible in water and which, in addition to a diluent or inert substance, also contain wetting agents, for example polyoxethylated alkylphenols, polyoxethylated fatty alcohols, alkylsulfonates or alkylphenolsulfonates and dispersants, for example sodium ligninsulfonate, sodium 2,2'-dinaphthylmethane-6,6'-bisulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleylmethyl taurinate besides the active 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 an addition of one or more emulsifiers. Emulsifiers which can be used are, for example, the following:
calcium alkylarylsulfonates, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers, such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide-ethylene oxide sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbital 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 substance onto adsorptive, granulated inert material or by applying active substance concentrates to the surface of carriers, such as sand, kaolinites or granulated inert material, by means of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Suitable active substances can 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.
In wettable powders, the concentration of active substance is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight is composed of conventional 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, on which compound is present in the liquid or solid form and on which granulation auxiliaries, fillers and the like are used.
Besides, the abovementioned formulations of active substances optionally contain the adhesives, wetting agents, dispersants, emulsifiers, penetrants, solvents, fillers or carriers which are conventional 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 in the case of some microgranules.
Preparations in the form of dust and granulated preparations as well as sprayable solutions are conventionally not diluted any further with other inert substances prior to use.
The application rate required varies with external conditions, such as temperature, humidity and the like. It can vary within wide limits, for example between 0.005 and 10.0 kg/ha or more of active ingredient, but is preferably between 0.01 and 5 kg/ha.

In general, the compositions according to the invention contain 1 to 95% by weight of the active substance of the formula 1.
They can be formulated in various ways, depending on the prevailing biological and/or chemical-physical parameters. The following are therefore suitable as possible formulations: wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SC), emulsions, sprayable solutions, oil- or water-based dispersions (SC), suspoemulsions (SC), 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 Edition 1986; van Falkenberg, "Pesticides Formulations", Marcel Dekker New York, 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, New York; Marschen, "Solvents Guide", 2nd Ed., Interscience, New York 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., New York 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte [Surface-Active Ethylene Oxide Adducts]", Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Kuchler, "Chemische Technologie", Volume 7, C. Hauser Verlag Munich, 4th Edition, 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, beside the active substance, also contain 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 hydrocarbons with an addition of one or more emulsifiers. Examples of emulsifiers which can be used are the following: calcium alkylarylsulfonates, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers, such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polylycol ethers, propylene oxide/ethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxethylene sorbitol esters.
Dusts are obtained by grinding the active substance with finely divided solid substances, for example talc, natural clays such as kaolin, bentonite, pyrophyllite, or diatomaceous earth. Granules can be produced either by spraying the active substance onto adsorptive, granulated inert material or by applying active substance concentrates to the surface of carriers, such as sand, kaolinites or granulated inert material, by means of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Suitable active substances can also be granulated in the manner which is customary for the production of fertilizer granules, if desired in the form of a mixture with fertilizers.
In wettable powders, the active substance concentration is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight is composed of customary formulation components. 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 of active substance, sprayable solutions approximately 2 to 20% by weight. In the case of granules, the active substance content partly depends on whether the active compound is in liquid or solid form and on which granulation auxiliary, fillers and the like are being used.
Besides, 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 commercially available, 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 prior to use.
The application rate required varies with external conditions, such as, inter alia, temperature and humidity. It can vary within wide limits, for example between 0.001 and 10.0 kg/ha or more of active ingredient, but it is preferably between 0.005 and 5 kg/ha.
The active substances according to the invention can be present in their 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.

Accordingly, the novel compounds of the formula 1 according to the invention can 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 orally to the animals, if appropriate together with the drinking water or the feed. Since they are excreted in an effective fashion in feces, this allows the development of insects in the feces of the animals to be prevented in a very simple manner. The dosages 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 easily be determined and chosen by the customary methods. The novel compounds can be employed for example in cattle at dosages of 0.01 to 1 mg/kg of body weight.

The examples which follow are intended to illustrate the invention without imposing any limitation thereon.
