Process for producing optically active γ-butyrolactone derivatives |
| abstract |
A process for producing an optically active gamma -butyrolactone derivative represented by formula (II): <IMAGE> (II) wherein R1 represents an alkyl group having from 1 to 10 carbon atoms or a substituted or unsubstituted phenyl group; and * indicates an asymmetric carbon atom, is disclosed, comprising enantioselectively hydrogenating a gamma -keto acid or an ester thereof represented by formula (I): <IMAGE> (I) wherein R1 and * are as defined above; and R2 represents a hydrogen atom or a lower alkyl group, in the presence of an optically active ruthenium-phosphine complex. The compounds (I) can be obtained at high optical purity through simple operations and a reduced number of steps. |
