Asymmetric acetylation of racemic halohydrins with vinyl acetate catalyzed by lipase from Pseudomonas sp. afforded the optically active beta-halo alcohols 1 and acetates 2 in high enantiomeric excess (68 to > 98%). The enzymatic kinetic resolution was performed on the preparative scale and the halo alcohols 1 and acetates 2 led to the optically active epoxides 3 after base treatment.
