The present invention relates to 2-substituted 7-aminoazolopyrimidines of the formula I
in which the substituents are as defined below:
Moreover, the invention relates to processes for preparing these compounds, to compositions comprising them and to their use for controlling phytopathogenic harmful fungi.
5,6-Dialkyl-7-aminoazolopyrimidines are proposed in a general manner in GB 1 148 629. Individual fungicidally active 5,6-dialkyl-7-aminoazolopyrimidines are known from EP-A 141 317. However, in many cases their activity is unsatisfactory. Based on this, it is an object of the present invention to provide compounds having improved activity and/or a wider activity spectrum.
We have found that this object is achieved by the compounds defined at the outset. Furthermore, we have found processes and intermediates for their preparation, compositions comprising them and methods for controlling harmful fungi using the compounds I.
The compounds of the formula I differ from those in the abovementioned publications by the specific embodiment of the substituent in the 2-position of the azolopyrimidine skeleton.
Compared to the known compounds, the compounds of the formula I are more effective against harmful fungi.
The compounds according to the invention can be obtained by different routes. Advantageously, the compounds according to the invention are obtained by converting substituted β-ketoesters of the formula II with an aminoazole of the formula III to give 7-hydroxyazolopyrimidines of the formula IV. The variables in formulae II and IV are as defined for formula I and the group R in formula II is C1-C4-alkyl; for practical reasons, preference is given here to methyl, ethyl or propyl.
The compounds of the formula IV are novel.
The reaction of the substituted β-ketoesters of the formula II with the aminoazoles of the formula III can be carried out in the presence or absence of solvents. It is advantageous to use solvents to which the starting materials are substantially inert and in which they are completely or partially soluble. Suitable solvents are in particular alcohols, such as ethanol, propanols, butanols, glycols or glycol monoethers, diethylene glycols or their monoethers, aromatic hydrocarbons, such as toluene, benzene or mesitylene, amides, such as dimethylformamide, diethylformamide, dibutylformamide, N,N-dimethylacetamide, lower alkanoic acids, such as formic acid, acetic acid, propionic acid, or bases, 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, triisopropylethylamine, tributylamine and N-methylpiperidine, N-methylmorpholine, pyridine, substituted pyridines, such as collidine, lutidine and 4-dimethylaminopyridine, and also bicyclic amines and mixtures of these solvents with water. Suitable catalysts are bases as mentioned above or acids such as sulfonic acids or mineral acids. With particular preference, the reaction is carried out in the absence of a solvent or in chlorobenzene, xylene, dimethyl sulfoxide or N-methylpyrrolidone. Particularly preferred bases are tertiary amines, such as triisopropylethylamine, tributylamine, N-methylmorpholine or N-methylpiperidine. The temperatures are from 50 to 300° C., preferably from 50 to 180° C., if the reaction is carried out in solution [cf. EP-A 770 615; Adv. Het. Chem. 57 (1993), 81ff].
The bases are generally employed in catalytic amounts; however, they can also be employed in equimolar amounts, in excess or, if appropriate, as solvent.
In most cases, the resulting condensates of the formula IV precipitate from the reaction solutions in pure form and, after washing with the same solvent or with water and subsequent drying they are reacted with halogenating agents, in particular chlorinating or brominating agents, to give the compounds of the formula V in which Hal is chlorine or bromine, in particular chlorine. The reaction is preferably carried out using chlorinating agents such as phosphorus oxychloride, thionyl chloride or sulfuryl chloride at from 50° C. to 150° C., preferably in excess phosphorus oxytrichloride at reflux temperature. After evaporation of excess phosphorus oxytrichloride, the residue is treated with ice-water, if appropriate with addition of a water-immiscible solvent. In most cases, the chlorinated product isolated from the dried organic phase, if appropriate after evaporation of the inert solvent, is very pure and is subsequently reacted with ammonia in inert solvents at from 100° C. to 200° C. to give the 7-aminoazolo[1,5-a]pyrimidines. The reaction is preferably carried out using a 1- to 10-molar excess of ammonia, under a pressure of from 1 to 100 bar.
The novel 7-aminoazolo[1,5-a]pyrimidines are, if appropriate after evaporation of the solvent, isolated as crystalline compounds, by digestion in water.
The β-ketoesters of the formula II can be prepared as described in Organic Synthesis Coll. Vol. 1, p. 248, and/or they are commercially available.
The intermediates of the formula V are novel.
Alternatively, the novel compounds of the formula I can be obtained by reacting substituted acyl cyanides of the formula VI in which R1 and R2 are as defined above with an aminoazole of the formula III.
The reaction can be carried out in the presence or absence of solvents. It is advantageous to use solvents to which the starting materials are substantially inert and in which they are completely or partially soluble. Suitable solvents are in particular alcohols, such as ethanol, propanols, butanols, glycols or glycol monoethers, diethylene glycols or their monoethers, aromatic hydrocarbons, such as toluene, benzene or mesitylene, amides, such as dimethylformamide, diethylformamide, dibutylformamide, N,N-dimethylacetamide, lower alkanoic acids, such as formic acid, acetic acid, propionic acid, or bases, such as those mentioned above, and mixtures of these solvents with water. The reaction temperatures are from 50 to 300° C., preferably from 50 to 150° C., if the reaction is carried out in solution.
The novel 7-aminoazolo[1,5-a]pyrimidines are, if appropriate after evaporation of the solvent or dilution with water, isolated as crystalline compounds.
Some of the substituted alkyl cyanides of the formula VI required for preparing the 7-aminoazolo[1,5-a]pyrimidines are known, or they can be prepared by known methods from alkyl cyanides and carboxylic acid esters using strong bases, for example alkali metal hydrides, alkali metal alkoxides, alkali metal amides or metal alkyls (cf.: J. Amer. Chem. Soc. 73 (1951), p. 3766).
Compounds of the formula I in which Rx is C1-C14-haloalkyl, C1-C12-haloalkoxy-C1-C12-alkyl, C1-C12-alkoxy-C1-C12-haloalkyl, C2-C12-haloalkenyl or C2-C12-haloalkynyl can be obtained by halogenation of corresponding halogen-free azolopyrimidines of the formula I, they are referred to as compounds I′. In formula I′, R1′ is a halogen-free group R1. In formula I″, R1″ is a halogenated group R1:
The halogenation is usually carried out at temperatures of from 0° C. to 200° C., preferably from 20° C. to 110° C., in an inert organic solvent in the presence of a free-radical initiator (for example dibenzoyl peroxide or azobisisobutyronitrile or under UV irradiation using, for example, an Hg vapor lamp) or an acid [cf. Synthetic Reagents, Vol. 2, pp. 1-63, Wiley Publishers, New York (1974)].
The reaction partners are generally reacted with one another in equimolar amounts. In terms of yield, it may be advantageous to employ an excess of halogenating agent, based on 1′.
Suitable halogenating agents are, for example, elemental halogens (for example Cl2, Br2, I2), N-bromosuccinimide, N-chlorosuccinimide oder dibromodimethylhydrantoin. The halogenating agents are generally employed in equimolar amounts, in excess or, if appropriate, as solvent.
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 generally not necessarily required, however, 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 use, for example in the treatment of plants in the treated plants, or in the harmful fungus to be controlled.

For seed treatment, use is usually made of water-soluble concentrates (LS), suspensions (FS), dustable powders (DS), water-dispersible and water-soluble powders (WS, SS), emulsions (ES), emulsifiable concentrates (EC) and gel formulations (GF). These formulations can be applied to the seed in undiluted form or, preferably, diluted. Application can be carried out prior to sowing.
The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, for example in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; the intention is to ensure in each case the finest possible distribution of the active compounds according to the invention.
Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.
The active compound concentrations in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1%.
The active compounds may also be used successfully in the ultra-low-volume process (ULV), by which it is possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.
Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active compounds, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the agents according to the invention in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.
Suitable adjuvants in this sense are in particular: organically modified polysiloxanes, for example Break Thru S 240®; alcohol alkoxylates, for example Atplus 245®, Atplus MBA 1303®, Plurafac LF 300® and Lutensol ON 30®; EO/PO block polymers, for example Pluronic RPE 2035® and Genapol B®; alcohol ethoxylates, for example Lutensol XP 80®; and sodium dioctylsulfosuccinate, for example Leophen RA®.

The procedures described in the following synthesis examples were used to prepare further compounds I by appropriate modification of the starting materials. The compounds thus obtained are listed in the table below, together with physical data.
At −70° C., a solution of 0.495 mol of butyllithium in hexane was added to a solution of 0.45 mol of decanitrile in 300 ml of tetrahydrofuran (THF), the mixture was then stirred at this temperature for about three hours and 0.45 mol of ethyl propionate was added. The mixture was then stirred at 20-25° C. for another about 16 hours, and 200 ml of water were then added and the mixture was acidified with dilute HCl solution. After phase separation, the organic phase was removed, washed with water and dried, and the solvent was removed. This gave 91 g of the title compound.
A solution of 1.6 g (13.5 mmol) of 5-chloro-1H-[1,2,4]triazol-3-ylamine, 2.8 g (13.5 mmol) of 4-cyanoundecan-3-one from Example 1 and a catalytic amount of p-toluenesulfonic acid in 50 ml of mesitylene was stirred at 180° C. for 4 hours, during which time the water of reaction destilled off. After removal of the solvent by distillation, the residue was digested in a dichloromethane/water mixture at 20 to 25° C. The insoluble components were filtered off and then recrystallized from methanol. This gave 2.9 g of the title compound in the form of colorless crystals of m.p. 202-203° C.
The fungicidal action of the compounds of the formula I was demonstrated by the following experiments:
The active compounds were prepared as a stock solution comprising 25 mg of active compound which was made up to 10 ml using a mixture of acetone and/or DMSO and the emulsifier Uniperol® EL (wetting agent having emulsifying and dispersing action based on ethoxylated alkylphenols) in a volume ratio of solvent:emulsifier of 99:1. The mixture was then made up to 100 ml with water. This stock solution was diluted with the solvent/emulsifier/water mixture described to the concentration of active compounds stated below.
Leaves of potted tomato plants were sprayed to runoff point with an aqueous suspension having the concentration of active compound stated below. The next day, the leaves were infected with an aqueous sporangia suspension of Phytophthora infestans. The plants were then placed in a water vapor-saturated chamber at temperatures between 18 and 20° C. After 6 days, the late blight on 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 500 ppm of the compound I-2 showed no infection, whereas the untreated plants were 90% infected.
In a further experiment, the plants which had been treated with 250 ppm of the compound I-15 or 1-16 showed an infection of at most 20%, whereas the untreated plants were 100% infected.
Leaves of potted vine were sprayed to runoff point with an aqueous suspension having the concentration of active compound stated below. The next day, the undersides of the leaves were inoculated with an aqueous sporangia suspension of Plasmopara viticola. The vines were then initially placed in a water vapor-saturated chamber at 24° C. for 48 hours and then in a greenhouse at temperatures between 20 and 30° C. for 5 days. After this time, the plants were once more placed in a humid chamber for 16 hours to accelerate the eruption of sporangiophores. The extent of the development of the infection on the undersides of the leaves was then determined visually.
In this test, the plants which had been treated with 500 ppm of the compound I-2, I-7 or I-8 showed an infection of at most 20%, whereas the untreated plants were 90% infected.
In a further experiment, the plants which had been treated with 250 ppm of the compounds I-15, I-16 or I-18 and the plants which had been treated with 63 ppm of the compound I-23 showed an infection of at most 20%, whereas the untreated plants were 100% infected.
