The effect of the acyl group of acylating agents on the enantioselectivity in the lipasecatalyzed transesterifications of racemie 2-[(N,N-dimethylearbamoyl)methyl]-3-eyelopenten-l-ol in diisopropyl ether was found 1o be significant. The enantioselectivity was enhanced markedly by changing the aeylat

โฆ Synopsis
The present research introduces the highly (S)-selective (E>>100) acylation at the secondary ring nitrogen of methyl pipecolinate as a novel resolution method with Candida antarctica lipase A. Catalysis by lipase B leads to reactions at the methyl ester function of the substrate in an almost non-enantioselective manner.
