DERIVATIVES OF ACRYLIC ACID, METHODS OF THEIR SYNTHESIS (VARIANTS), FUNGICIDE COMPOSITION, METHOD OF FUNGI CONTROL Russian patent published in 1998 - IPC

Abstract RU 2119483 C1

FIELD: organic chemistry and chemical technology. SUBSTANCE: products: derivatives of acrylic acid of the general formula (I) where A is hydrogen; R₂ is methyl and R¹ means 4-tert.-butylpyride-2-yl, 4-tert. -butylpyrimidine-2-yl, 5-methyl-6-isopropoxypyrimidine-4-yl or 4-(C_1-4-chlorofluoroalkyl)pyride-2-yl or isoquinoline that is optionally substituted with halogen or C₁-C₄-alkoxyl. Methods of synthesis of compounds of the formula (I) involve interaction of compound of the formula (II) in alkaline medium with compound of the formula (III) ( x - splitting off group) or compound of the formula (XV) with compound of the formula (XI) ONH₂ (X is -group). Fungicide composition has compound of the formula (I) at effective amount and fungicide acceptable carrier or diluting agent. Method of control over fungi involves treatment of plants with compound of the formula (I) or the above indicated composition. The synthesized compounds exhibit mainly fungicide activity with respect to fungal infections in plants. EFFECT: improved method of synthesis, enhanced antifungal activity of compounds synthesized. 6 cl, 4 dwg, 3 tbl, 7 ex
