DERIVATIVES OF 1H-3-ARYLPYRROLIDINE-2,4-DIONE, PARENT AND INTERMEDIATE COMPOUNDS FOR THEIR SYNTHESIS AND AGENT USED FOR CONTROL OF INSECTS AND MITES INJURING PLANTS Russian patent published in 2000 - IPC

FIELD: organic chemistry, insecticides, agriculture. SUBSTANCE: invention describes derivatives of 1H-3-arylpyrrolidine-2,4-dione of the formula (I) where A and B in common with carbon atom with which they bound mean 5- or 6-membered spirocycle broken by one heteroatom. Spirocycle has nitrogen, oxygen or sulfur atom as a heteroatom and can be substituted with R¹ or COR¹ groups near nitrogen atom; X and Y mean alkyl or halide atom; Z means alkyl; n = 0 or 1; G means groups , E or where E means ammonium ion; L and M mean O or S; R¹ means alkyl, alkenyl, alkoxyalkyl, cycloalkyl, substituted phenyl or heteroaryl; R² means alkyl, phenyl or benzyl; R³, R⁴, R⁵ mean alkyl or alkylthio-group; R⁶, R⁷ mean alkyl or in common with nitrogen atom with which they bound mean cycle that can be broken by oxygen atom. These compounds can be used as an active component for control of insects and mites injuring plants. Invention proposes also N-acylamino acid esters of the formula (II) that are the parent compounds for synthesis of compounds of the formula (I) and derivatives of aminonitrile of the formula (III) that are intermediate compounds for synthesis of compounds of the formula (I). Invention proposes an agent used for control of insects and mites injuring plants. EFFECT: improved method of synthesis, enhanced insecticide activity of an agent. 8 cl, 8 tbl, 95 ex
