AVERMECTIN B1 DERIVATIVES HAVING AN AMINOSULFONYLOXY SUBSTITUENT IN THE 4''-POSITION

摘要

A compound of formula (I) wherein the bond marked by formula (II) indicates either the S or the R isomer at the 4''−position; and wherein R1 is C1−C12alkyl, C3−C8cycloalkyl; or C2−C12alkenyl; R2 is, for example, hydrogen, unsubstituted or mono− to penta−substituted C1−C12alkyl or unsubstituted or mono− to penta−substituted C2−C12 alkenyl; R3 is, for example, hydrogen, C1−C12alkyl, mono− to penta−substituted C1−C12alkyl, unsubstituted or mono− to penta−substituted C3−C12cycloalkyl, or unsubstituted or mono− to penta−substituted C2−C12alkenyl; and wherein the substituents of the alkyl, alkenyl, alkynyl, alkylene, alkenylene and cycloalkyl radicals defined under R2 and R3 are selected, for example, from the group consisting of OH, halogen, halo−C1−C2alkyl, CN, NO2 and C2−C6alkynyl; and, where applicable, E/Z isomers, mixtures of E/Z isomers and/or tautomers, in each case in free form or in salt form; a process for the preparation of and the use of those compounds, their isomers and tautomers; starting materials for the preparation of the compounds of formula (I); pesticidal compositions in which the active ingredient has been selected from those compounds and their tautomers; and a method of controlling pests using those compositions are described.
