A practical and efficient method for the preparation of homoallylic alcohol and its successful enzymatic resolution has been developed. This lipase-catalyzed resolution process has been optimized with respect to different lipases and solvents. Moreover, Mitsunobu strategy has been applied to recover the unwanted isomer. Further optically enriched homoallylic alcohol has been employed for the synthesis of (-)-centrolobine.
