COMPOUNDS USEFUL AS FUNGICIDES AND METHOD FOR FUNGUS ERADICATION Russian patent published in 2004 - IPC

FIELD: organic chemistry, fungicides, agricultures.

SUBSTANCE: invention describes compounds of the general formula (I):

wherein R¹ means (C₁-C₁₀)-alkyl, hydrogen atom; R² and R³ can be different and represent hydrogen atom, (C₁-C₁₀)-alkyl possibly substituted with phenyl, (C₂-C₇)-alkenyl, cyano-group, -OR^a (wherein R^a represents (C₁-C₁₀)-alkyl), phenyl, (C₃-C₆)-cycloalkyl, -C(=O)R^c (wherein R^c represents (C₁-C₅)-alkyl); or R² and R³ in common with atoms joining them can form -(CH₂)₂-O-(CH₂)₂, -(CH₂)₄-, -(CH₂)-; R⁴ represents (C₁-C₁₀)-alkyl;, halogen atom; m = 0-3; R⁵ means (C₁-C₁₀)-alkyl, halogen atom, nitro-group; R⁶ represents phenyl, naphthyl, 5,6,7,8-tetrahydronaphthyl, (C₃-C₆)-cycloalkyl, 9-oxofluorenyl; A represents a direct bond, -O-, -S(O)_n-, -O-(A¹)_k-O-, -NR⁹A²-. Invention describes intermediate compound of the formula (XIIa)

Also, invention describes a method for eradication of fungi in infection foci. Prepared compounds elicit high activity with respect to such pathogens as tomato phytophtorosis, grape downy mildew and rice piriculariosis.

EFFECT: valuable agriculture properties of compounds.
