✦ Synopsis
The lipase-catalyzed asymmetric transesterification of racemic ¢x-methylene 13-1actones 1 with benzyl alcohol in organic media afforded the optically active I~-lactones and the corresponding 13-hydroxy esters 2 in excellent enantiomeric excess (ee 95-99%).

The lipase-catalyzed acetylation of a broad spectrum of configurations of the 2-hydroxy acids 1 were assigned by comparison of the gas-chromatographic data with that of racemic 2-hydroxy acids 1 to their 2-acetoxy acids 2 was shown to proceed with high enantioselectivity. Thus, the literature-known
