Kineticresolutions of α-methylene-β-hydroxy esters (Baylis–Hillman products) have been performed via enzymatic enantioselective transesterification with Pseudomonas sp. lipase (PSL), free or immobilized in poly(ethylene) oxide (PEO), silica gel and montmorillonite K10, under different reaction conditions. The corresponding (R)-(+)-acetates from alkyl-substituted racemic alcohols were obtained with
