&bgr;-keto esters are prepared by way of a lipase-catalyzed transesterification. The synthetic methodology provides a simple scheme for the synthesis of optically active &bgr;-keto esters that are useful building blocks and starting materials for natural product synthesis. Moreover, the methodology employs mild, solvent-free conditions. The methodology may also be employed for resolving racemic alcohols.
