FIELD: organic chemistry, herbicides, agriculture.
SUBSTANCE: invention describes a derivative of isoxaline represented by the general formula [I] wherein Q means a group represented by -S(O)n-(CR5R6)m- wherein n is a whole number from 0 to 2; m is a whole number from 1 to 3; each of R5 and R6 represents independently hydrogen atom, (C1-C)-alkyl group; R1 and R2 represent hydrogen atom, optionally substituted (C1-C8)-alkyl group, (C3-C)-cycloalkyl group, (C1-C6)-alkoxycarbonyl group, di-((C1-C6)-alkyl)-aminocarbonyl group, carboxyl group substituted with halogen atom, phenyl group; or R1 and R2 in common with carbon atom with which they are bound can form (C3-C7)-spirocycle; R3 and R4 represent hydrogen atom, (C1-C8)-alkyl group; or R1 and R2 in common with carbon atom with which they are bound can form 5-8-membered cycle; Y represents hydrogen atom, (C1-C6)-alkoxycarbonyl group, carboxyl group optionally substituted with (C1-C10)-alkyl group or phenyl group. Also, invention describes herbicide comprising above indicated derivative of isoxaline as an active component. Invention provides the excellent herbicide effect in its low dose in applying.
EFFECT: valuable properties of compounds.
