1,2,4-Triazolo[1,5a] Pyrimidines and Use Thereof for Controlling Plant-Pathogenic Fungi

The present invention relates to 1,2,4-triazolo[1,5a]pyrimidines, to their use for controlling phytopathogenic fungi and to crop protection compositions comprising, as active component, at least one such compound.

1,2,4-Triazolopyrimidines carrying an optionally substituted phenyl ring in the 6-position, a halogen atom in th 5-position and an amino group in the 7-position have been described in various publications of the prior art, for example in EP-A 71 792, EP-A 550 113, EP-A 834513 and WO-A 98/46608.

WO-A 99/41255 describes similar triazolopyrimidines which, instead of the amino group, carry an optionally substituted aliphatic or cycloaliphatic radical in the 7-position. The compounds are used as fungicides.

WO 03/004465 describes similar fungicidal 1,2,4-triazolo[1,5a]pyrimidines which carry an optionally substituted aliphatic, cycloaliphatic or aromatic radical in the 7-position and, instead of the halogen atom, an optionally substituted alkyl, alkenyl or alkynyl radical in the 5-position.

PCT/EP/03/14283 describes 5-methyl-6-(2-chloro-4-nitrophenyl)-7-(methylbutyl)-1,2,4-triazolo[1,5a]pyrimidine as intermediate for preparing 1,2,4-triazolo-[1,5a]pyrimidine compounds which carry a 4-acylaminophenyl group in the 6-position.

Some of the triazolopyrimidines known from the prior art are, with a view to their fungicidal activity, unsatisfactory, or they have unwanted properties, such as poor compatibility with crop plants.

Accordingly, it is an object of the present invention to provide novel compounds having improved fungicidal activity and/or crop plant compatibility.

and the agriculturally acceptable salts of the compounds of the formula 1.

Accordingly, the present invention provides the triazolopyrimidine compounds of the formula I and their agriculturally acceptable salts.

The present invention furthermore provides the use of the triazolopyrimidine compounds of the formula I and their agriculturally acceptable salts for controlling phytopathogenic fungi (=harmful fungi), and a method for controlling phytopathogenic fungi wherein the fungi or the materials, plants, the soil or seed to be protected against fungal attack are treated with an effective amount of a triazolopyrimidine compound of the formula I according to the invention and/or with an agriculturally acceptable salt of I.

The present invention furthermore provides a composition for controlling phytopathogenic fungi, which composition comprises at least one compound of the formula I and/or an agriculturally acceptable salt thereof and at least one solid or liquid carrier.

The compounds of the formula I according to the invention differ from the 1,2,4-triazolo[1,5a]pyrimidines known from the publications mentioned above by the substituent X on the phenyl group in the 6-position.

Depending on the substitution pattern, the compounds of the formula I may have one or more centers of chirality, in which case they are present as enantiomer or diastereomer mixtures. The present invention provides both the pure enantiomers or diastereomers and their mixtures. Suitable compounds of the formula I also include all possible stereoisomers (cis/trans isomers) and mixtures thereof.

Agriculturally useful salts are especially the salts of those cations or the acid addition salts of those acids whose cations and anions, respectively, have no adverse effect on the fungicidal action of the compounds I. Suitable cations are thus in particular the ions of the alkali metals, preferably sodium and potassium, of the alkaline earth metals, preferably calcium, magnesium and barium, of the transition metals, preferably manganese, copper, zinc and iron, and also the ammonium ion which, if desired, may carry one to four C₁-C₄-alkyl substituents and/or one phenyl or benzyl substituent, preferably diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium, furthermore phosphonium ions, sulfonium ions, preferably tri(C₁-C₄-alkyl)sulfonium, and sulfoxonium ions, preferably tri(C₁-C₄-alkyl)sulfoxonium.

Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogensulfate, sulfate, dihydrogenphosphate, hydrogenphosphate, phosphate, nitrate, bicarbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate, and the anions of C₁-C₄-alkanoic acids, preferably formate, acetate, propionate and butyrate. They can be formed by reacting I with an acid of the corresponding anion, preferably of hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid or nitric acid.

Compounds I in which X is nitro can be obtained by different routes; advantageously, the starting material used is 5-aminotriazole of the formula II which is condensed with dicarbonyl compounds of the formula III.

In scheme I, the substituents R¹, R², R and the index n are as defined above.

This reaction is usually carried out at temperatures of from 80° C. to 250° C., preferably from 120° C. to 180° C., without solvent or in an inert organic solvent in the presence of a base [cf. EP-A 770 615] or in the presence of acetic acid under the conditions known from Adv. Het. Chem. 57 (1993), 81 ff.

Suitable solvents are aliphatic carboxylic acids, for example C₁-C₄-carboxylic acids, such as acetic acid or propionic acid, aliphatic hydrocarbons, aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, ethers, nitriles, ketones, alcohols, and also N-methylpyrrolidone, dimethyl sulfoxide, dimethylformamide and dimethylacetamide. Particularly preferably, the reaction is carried out without solvent or in acetic acid, propionic acid, ethylene glycol dimethyl ether, chlorobenzene, xylene, dimethyl sulfoxide, N-methylpyrrolidone. It is also possible to use mixtures of the solvents mentioned.

Suitable bases are, in general, inorganic compounds, such as alkali metal and alkaline earth metal hydroxides, alkali metal and alkaline earth metal oxides, alkali metal and alkaline earth metal hydrides, alkali metal amides, alkali metal and alkaline earth metal carbonates, and also alkali metal bicarbonates, organometallic compounds, in particular alkali metal alkyls, alkylmagnesium halides and also alkali metal and alkaline earth metal alkoxides and dimethoxymagnesium, moreover organic bases, for example tertiary amines, such as trimethylamine, triethylamine, diisopropylethylamine, tributylamine and N-methylpiperidine, N-methylmorpholine, pyridine, substituted pyridines, such as collidine, lutidine and 4-dimethylaminopyridine, and also bicyclic amines. Particular preference is given to tertiary amines, such as diisopropylethylamine, tributylamine, N-methylmorpholine or N-methylpiperidine.

The bases are generally employed in catalytic amounts; however, they can also be employed in equimolar amounts, in excess or, if appropriate, as solvent.

The starting materials are generally reacted with one another in equimolar amounts. In terms of yield, it may be advantageous to employ an excess of base and diketone III, based on II.

The diketones III can be prepared analogously to processes known from the literature, for example as described in the publications mentioned above.

Compounds of the formula I in which X is NO₂and R¹, R², R and n are as defined above can also, as shown in scheme 2, be obtained by coupling 5-halotriazolo-pyrimidines of the formula IV (Y is halogen, in particular chlorine or bromine) with organometallic reagents of the formula V.

In formula V, M is a metal ion of valency y, such as, for example, B, Zn, Mg or Sn. In one embodiment of this process, the reaction is carried out with transition metal catalysis, such as Ni or Pd catalysis. This reaction can be carried out, for example, analogously to the following methods: J. Chem. Soc. Perkin Trans. 1 (1994), 1187, ibid. 1 (1996), 2345; WO-A 99/41255; Aust. J. Chem. 43 (1990), 733; J. Org. Chem. 43 (1978), 358; J. Chem. Soc. Chem. Commun. (1979), 866; Tetrahedron Lett. 34 (1993), 8267; ibid. 33 (1992), 413. The reaction may also be carried out without catalysts, in particular if M is Zn or Mg. The compounds IV are known from the publications cited at the outset. They are obtained, in particular, from 5,7-dichlorotriazolopyrimidines by introducing the radical R¹using organometallic processes similar to those described above.

The compounds of the formula I according to the invention in which X is nitro are also obtainable by reacting 5-halotriazolopyrimidines of the formula IV with substituted malonic esters of the formula VI in which R^xis C₁-C₄-alkyl, allyl, phenyl or benzyl, subsequent hydrolysis of the ester VII formed and decarboxylation of the carboxylic acid VIIa, as shown in scheme 3.

In scheme 3, Y is halogen, in particular chlorine or bromine, n, R and R¹are as defined for formula I and R^Ais hydrogen or C₁-C₃-alkyl which may be substituted by halogen, cyano, nitro or C₁-C₂-alkoxy. The nitro compounds IV are known from the publications cited at the outset.

In a preferred embodiment of the process according to the invention, R^Ais hydrogen or methyl, in particular hydrogen.

The reaction is usually carried out in the presence of an inert organic solvent. Examples of suitable organic inert solvents are those mentioned above, in particular nitriles, such as acetonitrile. Compound VI is usually employed in an equimolar amount or in up to 4-fold excess, based on the nitro compounds IV.

The starting materials VI are known from the literature [J. Am. Chem. Soc. 64 (1942), 2714; J. Org. Chem. 39 (1974), 2172; Helv. Chim. Acta 61 (1978), 1565], or they can be prepared in accordance with the literature cited.

The subsequent hydrolysis of the ester VII is carried out under generally customary conditions [cf.: Greene & Wuts, Protective Groups in Organic Synthesis, Wiley (1991), p. 224 ff.: cleavage of alkyl esters under Pd catalysis (p. 248); hydrogenolysis of benzyl esters (p. 251); cleavage of methyl or ethyl esters in the presence of lithium salts such as Lil (p. 232), LiBr or LiCl; or under acidic or alkaline conditions]. Depending on the structural elements R^A, (R)_nand R¹, alkaline or acidic hydrolysis of the compounds VII may be advantageous. Under the conditions of ester hydrolysis, there may already be complete or partial decarboxylation to I.

The decarboxylation is usually carried out at temperatures of from 20° C. to 180° C., preferably from 50° C. to 120° C., in an inert solvent, if appropriate in the presence of an acid.

Suitable acids are hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, p-toluenesulfonic acid. Suitable solvents are water, aliphatic hydrocarbons, such as pentane, hexane, cyclohexane and petroleum ether, aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as methylene chloride, chloroform and chlorobenzene, ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran, nitrites, such as acetonitrile and propionitrile, ketones, such as acetone, methyl ethyl ketone, diethyl ketone and tert-butyl methyl ketone, alcohols, such as methanol, ethanol, n-propanol, isopropanol, n-butanol and tert-butanol, and also dimethyl sulfoxide, dimethylformamide and dimethylacetamide; particularly preferably, the reaction is carried out in hydrochloric acid or acetic acid. It is also possible to use mixtures of the solvents mentioned.

The compounds of the formula I according to the invention in which X is nitro can also be obtained by nitrating the compounds of the formula VIII, as shown in scheme 4.

In scheme 4, R¹, R², R and n are as defined above. Suitable nitrating agents are, for example, nitric acid in various concentrations, including concentrated and fuming nitric acid, mixtures of sulfuric acid and nitric acid, and furthermore acetyl nitrates and alkyl nitrates.

The reaction can be carried out either in the absence of a solvent in an excess of the nitrating agent, or in an inert solvent or diluent, suitable solvents or diluents being, for example, water, mineral acids, organic acids, halogenated hydrocarbons, such as methylene chloride, anhydrides, such as acetic anhydride, and mixtures of these solvents.

The starting material VIII and the nitrating agent are expediently employed in approximately equimolar amounts; however, for an optimum conversion of the starting material it may be advantageous to use an excess of nitrating agent of up to about 10 times the molar amount, based on the starting material VIII. If the reaction is carried out without solvent in the nitrating agent, this is present in an even greater excess.

The reaction temperature is usually from −100° C. to 200° C., preferably from −30 to 50° C.

The starting materials VIII are known from WO 03/004465 or can be prepared analogously to the processes described therein.

The compounds of the formula I according to the invention in which X is C(S)NR³R⁴can also be obtained by different routes, for example from the carboxamide compounds IX by reaction with a sulfurizing agent, as shown in scheme 5.

In scheme 5, R¹, R², R³, R⁴, R and n are as defined above. Examples of suitable sulfurizing agents are organophosphorus sulfides, such as Lawesson's reagent (2,2-bis-(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide), organotin sulfides, such as bis(tricyclohexyltin)sulfide, or phosphorus pentasulfide (see also J. March, Advanced Organic Synthesis, 4th edition, Wiley Interscience 1992, p. 893 f. and the literature cited therein). The reaction can be carried out in a solvent or neat. Suitable solvents are the inert organic solvents mentioned above, and also pyridine and the like. The temperature required for the reaction is generally above room temperature and in particular in the range from 50 to 200° C.

The starting materials IX are known from WO 03/004465 or can be prepared analogously to the processes described therein. The starting materials IX can also be prepared according to the synthesis shown in scheme 6:

In scheme 6, R¹, R², R and n are as defined above.

In a first step a), a nitrile compound of the formula X is partially hydrolyzed. The hydrolysis of the nitrile X can be carried out either under acidic conditions, for example in the presence of a mineral acid, such as hydrochloric acid, or under alkaline conditions, for example in alkaline hydrogen peroxide solution. This gives a carboxamide IX in which R³and R¹are hydrogen.

The amide IX is then, if appropriate, mono- or dialkylated at the amide nitrogen atom in a second step b) by reaction with an alkylating agent. Suitable alkylating agents are, for example, C₁-C₆-alkyl halides, di-C₁-C₆-alkyl sulfates or C₁-C₆-alkyl phenylsulfonates, where the phenyl radical may, if appropriate, carry one or two radicals selected from the group consisting of nitro and C₁-C₆-alkyl. In general, an at least equimolar amount of alkylating agent, based on the acid amide IX, is employed. The alkylation is usually carried out in the presence of a base. Suitable bases are, in principle, all compounds which are capable of deprotonating the amide nitrogen. Suitable bases are, for example, alkali metal and alkaline earth metal hydroxides, such as sodium hydroxide, potassium hydroxide, lithium hydroxide and magnesium hydroxide, alkali metal and alkaline earth metal oxides, such as calcium oxide, alkali metal or alkaline earth metal carbonates, such as lithium carbonate, sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate. Based on the acid amide IX, the base can be employed in substoichiometric, superstoichiometric or equimolar amounts.

The nitriles X are likewise known from WO 03/004465 or can be prepared from the compounds I in which X is nitro by reducing the nitro group to the amino group, conversion of the amino group into a diazonium group and subsequent Sandmeyer reaction with copper(I) cyanide.

The compounds of the formula I according to the invention in which X is C(═S)NH₂can also be prepared, for example, by reacting the nitriles X with hydrogen sulfide, as shown in scheme 7.

In scheme 7, (R)_n, R¹and R²are as defined above. In general, the reaction is carried out in the presence of a solvent or diluent. Suitable solvents or diluents are, for example, aromatic amines, such as pyridine, substituted pyridines, such as collidine and lutidine, or tertiary amines, such as trimethylamine, triethylamine, triisopropylamine and N-methylpiperidine.

The reaction of the nitrile X with hydrogen sulfide is advantageously carried out at from 0° C. to 100° C., in particular from 10° C. to 50° C.

The aminothiocarbonylphenyltriazolopyrimidines I {X═—C(S)NH₂} obtained in this manner can then, if appropriate, be mono- or dialkylated at the amide nitrogen atom in a subsequent step, by reaction with an alkylating agent. Suitable alkylating agents are, for example, C₁-C₆-alkyl halides, di-C₁-C₆-alkyl sulfates or C₁-C₆-alkyl phenylsulfonates, where the phenyl radical may, if appropriate, carry one or two radicals selected from the group consisting of nitro and C₁-C₆-alkyl. In general, an at least equimolar amount of alkylating agent, based on the thioamide I, is employed.

The alkylation is usually carried out in the presence of a base. Suitable bases are, in principle, all compounds capable of deprotonating the amide nitrogen. Suitable bases are, for example, alkali metal and alkaline earth metal hydroxides, such as sodium hydroxide, potassium hydroxide, lithium hydroxide and magnesium hydroxide, alkali metal and alkaline earth metal oxides, such as calcium oxide, alkali metal or alkaline earth metal carbonates, such as lithium carbonate, sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate. Based on the thioamide I, the base can be employed in substoichiometric, superstoichiometric or equimolar amounts.

Compounds of the formula I in which X is a group —C(═N—OR⁵)(NR⁶R⁷) can be prepared, for example, by reacting compounds of the formula I in which X is —C(S)NR³R⁴with hydroxylamine hydrochloride followed, if appropriate, by alkylation. Here, R³and R⁴have the same meanings as R⁶and R⁷. With respect to suitable alkylating agents, solvents and bases, reference is made to what was said above in its entirety.

Compounds of the formula I in which X is a group —C(═N—NR⁸R⁹)(NR¹⁰R¹¹) can be prepared, for example, by reacting compounds of the formula I in which X is —C(S)NR³R⁴with substituted hydrazine derivatives. Here, R³and R⁴have the same meanings as R¹⁰and R¹¹.

Compounds of the formula I in which X is a group —C(═N—OR⁵)(NH₂) or —C(═N—NR⁸R⁹)—NH₂can advantageously also be prepared from the nitrile X using the methods shown in scheme 8. Here, the nitrile X may, firstly, be reacted directly with NH₂OR⁵(where R⁵is as defined above) or its salts in aqueous solution, preferably in water or water/alkanol mixtures, if appropriate in the presence of a base, to give the compound I where X═—C(═N—OR⁵)(NH₂), or with H₂N—NR⁸R⁹to give the compound I where X═—C(═N—NR⁸R⁹)—NH₂. This reaction can be carried out, for example, analogously to the following methods: WO 00/17156, WO 00/24740, U.S. Pat. No. 5,104,991, U.S. Pat. No. 4,379,158, Journal of Organic Chemistry 58 (16) (1993), 4331, Acta Pol. Pharm. 36 (1979), 155. Secondly, compounds of the formula I in which X is a group —C(═N—OR⁵)(NH₂) or a group —C(═N—NR⁸R⁹)—NH₂can also be prepared by reacting the nitrile X with an alcohol R¹²—OH, such as a C₁-C₄-alkanol, and hydrogen chloride in the absence of water to give an imidocarboxylic ester XI, followed by reaction of the resulting imidocarboxylic ester XI with NH₂OR⁵, giving the compound I where X═—C(═N—OR⁵)(NH₂), or with H₂N—NR⁸R⁹(in which R⁵, R⁸and R⁹are as defined above), giving the compound I where X═—C(═N—NR⁸R⁹)—NH₂. The preparation of the imidocarboxylic ester XI can be carried out, for example, analogously to the conditions known from Jerry March, 3rd edition, John Wiley & Sons, New York, 1985, p. 792.

In scheme 8, R¹, R², (R)_nare as defined above; R¹²is, for example, C₁-C₄-alkyl. The resulting compounds I in which X is a group —C(═N—OR⁵)(NH₂) or —C(═N—NR⁸R⁹)NH₂can be alkylated in a known manner giving compounds I in which X is —C(═N—OR⁵)(NR⁶R⁷) or —C(═N—NR⁸R⁹)(NR¹⁰R¹¹), where R⁵, R⁶, R⁷, R⁸, R⁹, R¹⁰and R¹¹are as defined above. With respect to suitable processes for the alkylation, reference is made to what was said above in its entirety.

The reaction mixtures are worked up in a customary manner, for example by mixing with water, separating the phases and, if appropriate, chromatographic purification of the crude products. Some of the intermediates and end products are obtained in the form of colorless or slightly brownish viscous oils which are purified or freed from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, purification can also be carried out by recrystallization or digestion.

If individual compounds I cannot be obtained by the routes described above, they can be prepared by derivatization of other compounds I.

If the synthesis yields mixtures of isomers, a separation is, however, generally not necessarily required since in some cases the individual isomers can be interconverted during work-up for use or during application (for example under the action of light, acids or bases). Such conversions may also take place after the application, for example in the treatment of plants, in the treated plant or in the harmful fungus or animal pests to be controlled.

The compounds I are suitable as fungicides. They are distinguished by an outstanding effectiveness against a broad spectrum of phytopathogenic fungi from the classes of the Ascomycetes, Deuteromycetes, Oomycetes and Basidiomycetes. Some are systemically effective and they can be used in plant protection as foliar and soil fungicides.

They are particularly important in the control of a multitude of fungi on various cultivated plants, such as wheat, rye, barley, oats, rice, corn, grass, bananas, cotton, soya, coffee, sugar cane, vines, fruits and ornamental plants, and vegetables, such as cucumbers, beans, tomatoes, potatoes and cucurbits, and on the seeds of these plants.

The compounds I are employed by treating the fungi or the plants, seeds, materials or soil to be protected against fungal attack with a fungicidally effective amount of the active compounds. The application can be carried out both before and after the infection of the materials, plants or seeds by the fungi.

The fungicidal compositions generally comprise between 0.1 and 95%, preferably between 0.5 and 90%, by weight of active compound.

Activity Against Early Blight of Tomato Caused by Altemara Solani

Leaves of potted plants of the cultivar “St. Pierre beef tomato” were sprayed to run off point with an aqueous suspension having the concentration of active compounds stated below. The next day, the leaves were infected with an aqueous zoospore suspension of Alternaria solani in 2% biomalt solution having a density of 0.17×10⁶spores/ml. The plants were then placed in a water-vapor-saturated chamber at temperatures of between 20 and 22° C. After 5 days, the infection on the leaves of the untreated, but infected control plants had developed to such an extent that the infection could be determined visually in %.

In this test, the plants which had been treated with 250 ppm of the title compound from example 1 were less than 5% infected, whereas the untreated plants were 80% infected.

Use Example 2
Activity Against Gray Mold on Bell Pepper Leaves Caused by Botrytis Cinerea

Bell pepper seedlings of the cultivar “Neusiedler Ideal Elite” were, after 2-3 leaves were well developed, sprayed to runoff point with an aqueous suspension having the concentration of active compound stated below. The next day, the treated plants were inoculated with a spore suspension of Botrytis cinerea which contained 1.7×10⁶spores/ml in a 2% strength aqueous biomalt solution. The test plants were then placed in a climatized chamber at 22-24° C. and high atmospheric humidity. After 5 days, the extent of the fungal infection on the leaves could be determined visually in %.

In this test, the plants which had been treated with 250 ppm of the title compound from example 1 showed no infection, whereas the untreated plants were 90% infected.
