ABSTRACT:
A process for isomerizing optically active .alpha.-cyano-3-phenoxybenzyl 2-(4-chlorophenyl)isovalerate at the asymmetric carbon atom of the 3-phenoxybenzyl moiety, and a process for obtaining (S)-.alpha.-cyano-3-phenoxybenzyl (S)-2-(4-chlorophenyl)isovalerate from (R, S)-.alpha.-cyano-3-phenoxybenzyl (S)-2-(4-chlorophenyl)isovalerate.
