Abstract

Enzymatic kinetic resolution studies of (±)-4-hydroxycyclopent-2-en-1-one 2 were taken up in organic solvents by transesterification with vinyl acetate and alcoholysis of its acetate 3 as an alternative to the desymmetrization of meso-cyclopentenediol to provide faster and economic access to enantiomerically pure 4-(R)-tert-butyldimethylsilyloxycyclopent-2-en-1- one 1. Parameters were screened using Lipozyme IM® as catalyst. Although ...
