Process for preparing optically active alpha -cyano-3-phenoxybenzyl 2-(4-chlorophenyl)isovalerate |
| 摘要 |
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.
