Description

The present application relates to novel acylated 4-amino-pyridine derivatives, to processes for their preparation and to their use for controlling animal pests and as fungicides.

It is already known that certain substituted 4-amino-pyridines have insecticidal properties (cf., for example, WO 93/04580, WO 96/08475, WO 96/10016, WO 96/14301 or WO 96/33975).

However, in particular at low application rates and concentrations, the activity and/or activity spectrum of these compounds is not always entirely satisfactory.

This invention provides novel acylated 4-amino-pyridines of the formula (I)

in which

R 1 represents alkyl, halogenoalkyl, alkoxy, alkylthio, alkoxyalkyl, alkylthioalkyl or optionally substituted cycloalkyl,

R 2 represents hydrogeni, alkyl, alkoxy, halocen, cyano, aminothiocarbonyl or optionally substituted aryl,

R 3 represents alkyl, alkenyl, optionally substituted cycloalkyl or represents in each case optionally substituted aryl or arylalkyl,

R 4 represents one of the radicals —CO—NR 5 R 6 , —CS—NR 7 R 8 , —C(═NH)—NH—OR 9 , —C(═N—OH)—OH, —CHO, —CH═N—OR 10 and —C(═N—OR 11 )—R 12 or represents an optionally substituted heterocycle

 where

R 5 to R 12 independently of one another represent hydrogen or alkyl,

A represents CH, CX 2 or N,

X 1 and X 2 independently of one another represent halogen, alkyl, alkoxy or halogenoalkyl and

m represents 0, 1, 2, 3 or 4,

n represents 0, 1, 2 or 3 and in the case A=CX 2 also represents 4,

including the pyridine N-oxides and salts which are protonated at the pyridine nitrogen.

Furthermore, it has been found that the compounds of the formula (I) are obtained when compounds of the formula (II)

in which

R 1 , R 2 , R 3 , A, X 1 , X 2 , m and n are as defined above

are derivatized at the nitrile group by generally known methods of organic chemistry.

Finally, it has been found that the novel compounds of the formula (I) have strongly pronounced biological properties and are suitable especially as fungicides and for controlling animal pests, in particular insects, arachnids and nematodes, which are encountered in agriculture, in forests, in the protection of stored products and materials and in the hygiene sector.

Surprisingly, the acylated 4-amino-pyridines according to the invention exhibit considerably better activity against animal pests than known compounds of a similar constitution.

Using, for example, N-(3-chloro-2-ethyl-pyridin-4-yl)-N-isopropoxycarbonyl-4-(4-cyanophenoxy)phenylacetamide as starting material and diphenyldithiophosphinic acid as derivatizing (sulphurizing) agent, the course of the process according to the invention can be represented by the following reaction scheme:

The compounds of the formula (II) required as starting materials for carrying out the process according to the invention are known (cf. WO 96/33975) and/or can be obtained by the processes described therein.

The compounds of the formula (I) according to the invention can also be obtained in a generally known manner (cf. WO 96/33975 and WO 93/04580) according to the following general reaction scheme 1:

where

R 1 to R 4 , A, X 1 , X 2 , m and n are as defined above and

X represents a leaving group, for example halogen, in particular chlorine or bromine.

The derivatization of the nitrile group according to the process according to the invention, i.e. the synthesis of compounds in which R 4 represents the radicals according to the invention, can in principle also be carried out as early as at the stages according to compounds of the formulae (IV) and (V) mentioned in reaction scheme 1.

The synthesis steps required to this end are standard methods of organic chemistry and generally known from the literature—cf. also the general reaction scheme 2 below:

where Ar represents the following radicals:

and

Hal represents halogen, preferably chlorine or bromine,

R represents C 1 -C 4 -alkyl, preferably methyl, ethyl, n- or i-propyl and

Y and Z represent, for example, halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or C 1 -C 4 -halogenoalkyl having 1 to 5 identical or different halogen atoms, particularly preferably represent fluorine, chlorine, bromine, methyl, methoxy or trifluoromethyl.

Aromatic nitriles (VI) can be converted, for example, by hydrolysis into the carboxamides (VII) (cf., for example, JACS 78, 5416 (1956) and 79, 2530 (1957)).

Using sulphurizing agents such as, for example, phosphorus pentasulphide, Lawessons reagent or diphenylditliophosphinic acid [Ph 2 P(═S)—SH, cf., for example, THL 1851 (1981)], it is possible to convert aromatic nitrites (VI) into the thioamides (VIII) (cf., for example, Sulphur reports 297 (1992)).

The Hantzsch synthesis of the thiazoles (IX) by reaction of the thioamides (VIII) with halogenoketones is a standard reaction of organic chemistry.

The 1,2,4-oxadiazoles (XI) are obtained by reacting the aromatic nitriles (VI) with hydroxylamine to (Tite the compounds (X), followed by cyclization with appropriate ortho esters.

Reaction of the carboxylic esters (XII), obtainable from the aromatic nitrites (VI) by Pinner reaction, with hydroxylamine and sodium ethoxide to give the compounds (XIII) and subsequent cyclization with dibromoethane gives 1,4,2-dioxazines (XIV).

The pyridine N-oxides and the salts of the compounds of the formula (I) which are protonated at the pyridine nitrogen can be obtained in a generally customary and known manner, for example by reacting the compounds of the formula (I) with an oxidizing agent such as, for example, m-chloroperbenzoic acid or with organic or inorganic acids such as, for example, trifluoroacetic acid, hydrogen bromide or hydrogen chloride.

Work-up and isolation of the intermediates and end products in question is carried out in a generally known manner.

They can be employed particularly successfully for controlling phytopathogenic insects, such as, for example, against the caterpillars of the owlet moth ( Spodoptera exigua ).

The active compounds can be converted into the customary formulations such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

If the extender used is water, it is also possible to employ for example organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.

Suitable solid carriers are:

for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkylsulphates, arylsulphonates as well as protein hydrolysates; as dispersing agents there are suitable: for example lignini-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

The active compound of the invention can be present in its commercially customary formulations and in the use forms prepared from these formulations, in a mixture with other active compounds, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth regulators or herbicides.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, is also possible.

The active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms prepared from these formulations, as a mixture with synergists. Synergists are compounds which increase the action of the active compounds without it being necessary for the synergist added to be active itself.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The compounds are employed in a customary manner appropriate for the use forms.

When used against hygiene pests and pests of stored products, the active compound is distinguished by an excellent residual action on wood and clay as well as a good stability to alkali on limed substrates.

The active compounds according to the invention are not only active against plant, hygiene and stored-product pests, but also, in the veterinary medicine sector, against animal parasites (ectoparasites), such as ixodid ticks, argasid ticks, scab mites, trombiculid mites, flies (stinging and sucking), parasitic fly larvae, lice, hair lice, bird lice and fleas.

The active compounds of the formula (I) according( to the invention are also suitable for controlling arthropods which attack agricultural livestock, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese, honey bees, other domestic animals, such as, for example, dogs, cats, cage birds, aquarium fish, and so-called experimental animals such as, for example, hamsters, guinea-pigs, rats and mice. By controlling these arthropods, it is intended to reduce mortality and decreased performance (in meat, milk, wool, hides, eggs, honey and the like), so that more economical and simpler animal keeping is made possible by using the active compounds according to the invention.

In the veterinary sector, the active compounds according to the invention are used in a known manner by enteral administration, for example in the form of tablets, capsules, drinks, drenches, granules, pastes, boluses, the feed-through method, suppositories, by parenteral administration, such as, for example, by means of injections (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal application, by dermal administration, for example in the form of dipping or bathing, spraying, pouring-on and spotting-on, washing, dusting, and with the aid of shaped articles which comprise active compound, such as collars, ear tags, tail marks, limb bands, halters, marking devices and the like.

When administered to livestock, poultry, domestic animals and the like, the active compounds of the formula (I) can be used as formulations (for example powders, emulsions, flowables) which comprise the active compounds in an amount of 1 to 80% by weight, either directly or after dilution by a factor of 100 to 10,000, or they may be used in the form of a chemical bath.

Furthermore, it has been found that the compounds of the formula (I) according to the invention have a potent insecticidal action against insects which destroy industrial materials.

The following insects may be mentioned by way of example and as being preferred, but without any limitation:

Beetles, such as

Hylotrupes bajulus, Chlorophorus pilosis, Anobium punctatum, Xestobium rufovillosum, Ptilinus pecticornis, Denidrobium pertinex, Ernobius mollis, Priobium carpini, Lyctus brunneus, Lyctus africanus, Lyctus planicollis, Lyctus linearis, Lyctus pubescens, Trogoxylon aequale, Minthes rugicollis , Xyleborus spec., Tryptodendron spec., Apate monachus, Bostrychus capucins, Heterobostrychus brunneus , Sinoxylon spec., Dinoderus minutus.

Bristiletals, such as Lepisma saccarina.

Industrial materials are to be understood as meaning, in the present context, non-living materials such as, preferably , synthetic materials, glues, sizes, paper and board, leather, wood and timber products, and paint.

The materials to be very particularly protected against attack by insects are wood and timber products.

Wood and timber products which can be protected by the composition according to the invention or mixtures comprising such a composition are to be understood as meaning, for example, construction timber, wooden beams, railway sleepers, bridge components, jetties, wooden vehicles, boxes, pallets, containers, telephone poles, wood cladding, windows and doors made of wood, plywood, particle board, joiner's articles, or wood products which, quite generally, are used in the construction of houses or in joinery.

The active compounds can be used as such, in the form of concentrates or generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersant and/or binder or fixative, water repellent, if appropriate desiccants and UV stabilizers and, if appropriate, colorants and pigments and other processing auxiliaries.

The insecticidal compositions or concentrates used for the protection of wood and wooden materials comprise the active compound according to the invention at a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the species and the occurrence of the insects and on the medium. The optimum rate of application can be determined upon use in each case by test series. However, in general, it suffices to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be protected.

The solvent and/or diluent used is an organochemical solvent or solvent mixture and/or an oily or oil-type organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.

Organochemical solvents which are preferably employed are oily or oil-type solvents having an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C. Substances which are used as such oily and oil-type solvents which have low volatility and are insoluble in water are suitable mineral oils or their aromatic fractions, or mineral-oil-containing solvent mixtures, preferably white spirit, petroleum and/or alkylbenzene.

Substances which are advantageously used are mineral oils with a boiling range of 170 to 220° C., white spirit with a boiling range of 170 to 220° C., spindle oil with a boiling range of 250 to 350° C., petroleum or aromatics of boiling range 160 to 280° C., essence of turpentine and the like.

In a preferred embodiment, liquid aliphatic hydrocarbons with a boiling range of 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons with a boiling range of 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.

The organic oily or oil-type solvents of low volatility having an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., can be partially replaced by organochemical solvents of high or medium volatility, with the proviso that the solvent mixture also has an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

In a preferred embodiment, part of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Substances which are preferably used are aliphatic organochemical solvents having hydroxyl and/or ester and/or ether groups, such as, for example, glycol ether, esters and the like.

The organochemical binders used within the scope of the present invention are the synthetic resins and/or binding drying oils which are known per se and can be diluted with water and/or are soluble or dispersible or emulsifiable in the organochemical solvents employed, in particular binders composed of, or comprising, an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenol resin, hydrocarbon resin, such as indene/coumarone resin, silicone resin, drying vegetable and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Up to 10% by weight of bitumen or bituminous substances can also be used as binders. In addition, colorants, pigments, water repellents, odour-masking substances and inhibitors or anticorrosives known per se and the like can also be employed.

The composition or the concentrate preferably comprises, in accordance with the invention, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil as the organochemical binder. Preferably used according to the invention are alkyd resins with an oil content of over 45% by weight, preferably 50 to 68% by weight.

All or some of the abovementioned binder can be replaced by a fixative (mixture) or a plasticizer (mixture). These additives are intended to prevent volatilization of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of binder employed).

The plasticizers are from the chemical classes of the phthalic esters, such as dibutyl phthalate, dioctyl phthalate or benzyl butyl phthalate, phosphoric esters, such as tributyl phosphate, adipic esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or relatively high-molecular-weight glycol ethers, glycerol esters and p-toluene-sulphonic esters.

Fixatives are chemically based on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether, or ketones, such as benzophenone or ethylene benzophenone.

Particularly suitable as a solvent or diluent is also water, if appropriate as a mixture with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersants.

Particularly effective protection of wood is achieved by large-scale industrial impregnation processes, for example vacuum, double-vacuum or pressure processes.

If appropriate, the ready-to-use compositions can additionally comprise further insecticides and additionally one or more fungicides.

Suitable additional components which may be admixed are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in that document are expressly part of the present application.

Very particularly preferred components which may be admixed are insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron and triflumuron, and fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorofluanide, tolylfluanide, 3-iodo-2-propinylbutyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.
