Patent ID: 8114991

Claim:
An optically active compound of formula (I), in which: R 1 is H, halogen, (C 1 -C 6 )alkyl, (C 1 -C 6 )haloalkyl, [(C 1 -C 4 )alkoxy](C 1 -C 6 )alkyl, (C 3 -C 6 )cycloalkyl which is unsubstituted or substituted by one or more radicals selected from the group consisting of halogen, (C 1 -C 4 )alkyl and (C 1 -C 4 )haloalkyl, or is (C 2 -C 6 )alkenyl, (C 2 -C 6 )alkynyl, (C 2 -C 6 )haloalkenyl, (C 4 -C 6 )cycloalkenyl, (C 4 -C 6 )halocycloalkenyl, (C 1 -C 6 )alkoxy or (C 1 -C 6 )haloalkoxy; R 2 is H, halogen, (C 1 -C 6 )alkyl or (C 1 -C 4 )alkoxy; or R 1 and R 2 can together with the attached carbon atom form a (C 3 -C 6 )cycloalkyl or (C 4 -C 6 )cycloalkenyl ring; R 3 is H, (C 1 -C 6 )alkyl, (C 1 -C 4 )alkoxy or halogen; R 4 and R 5 are each independently H, (C 1 -C 4 )alkyl, (C 1 -C 4 )haloalkyl, (C 3 -C 4 )alkenyl, (C 3 -C 4 )haloalkenyl, (C 3 -C 4 )alkynyl, (C 3 -C 4 )haloalkynyl or an acyl radical; R 6 is (C 1 -C 6 )alkyl; R 7 , R 8 , R 9 and R 10 are each independently H, (C 1 -C 4 )alkyl, (C 1 -C 3 )haloalkyl, halogen, (C 1 -C 3 )alkoxy, (C 1 -C 3 )haloalkoxy or CN; A is CH 2 , O or a direct bond; and the stereochemical configuration at the marked 1R position has a stereochemical purity of from 60 to 100% (R), the stereochemical configuration at the marked 2S position has a stereochemical purity of from 60 to 100% (S), provided that R 1 , R 2 and R 3 are structurally different or provided that at least two of R 1 , R 2 and R 3 are structurally identical, or an agriculturally acceptable salt thereof.
