SUBSTITUTED ISOXAZOLINES, METHOD FOR THEIR PREPARING, AGENT FOR PROTECTING CEREALS AGAINST DAMAGING EFFECT OF SOME HERBICIDES AS DERIVATIVES OF PHENOXYPROPIONIC ACID AND METHOD FOR PROTECTING CEREALS AGAINST PHYTOTOXIC ADVERSE EFFECT OF SOME HERBICIDES OF PHENOXYPROPIONIC ACID, SULFONULUREA, BENZOYLCYCLOHEXANEDIONE AND BENZOYLISOXAZOLE Russian patent published in 2004 - IPC

FIELD: organic chemistry, agriculture.

SUBSTANCE: invention proposes substituted isoxazolines of the general formula (I) or their salts:

wherein R¹ means carboxyl, carboxamide, N-(4-chlorophenyl)-aminocarbonyl, N,N-dimethylaminocarbonyl, N-methylaminocarbonyl, residue of formulas:

wherein R means hydrogen atom, alkyl with 1-18 carbon atoms that can be substituted with halide, hydroxy-group, alkoxy-group with 1-8 carbon atoms, alkylthio-group with 1-8 carbon atoms, alkoxycarbonyl with 1-8 carbon atoms in alkoxy moiety or phenyl; R⁵ and R⁶ are similar or different and mean independently of one another alkyl with 1-6 carbon atoms; or R⁵ and R⁶ form in common alkylene chain with 2-4 carbon atoms; R² means hydrogen atom, alkyl with 1-18 carbon atoms that can be substituted with cyano-group or alkoxycarbonyl with 1-4 carbon atoms in alkoxyl group, cycloalkyl with 3-8 carbon atoms, alkenyl with 2-8 carbon atoms, alkoxy-group with 1-18 carbon atoms or alkylthio-group with 1-18 carbon atoms; R³ and R⁴ mean independently of one another alkyl with 1-4 carbon atoms, cycloalkyl with 3-12 carbon atoms that are useful as antidotes for herbicides in cultural plants. Substituted isoxazolines of above given formula (I) or their salts are prepared by interaction of compound of the general formula (II): R³R⁴C=CHR² wherein R², R³ and R⁴ have above given values with nitrile oxide of the general formula (III): ^(-)O-N=⁽⁺⁾C-R. New substituted isoxazolines elicit the stronger effect protective cultured plants, in particular, cereals, against effect of herbicides on them.

EFFECT: improved preparing method, valuable properties of compounds.
