The highly enantioselective kinetic resolution of a racemic primary alcohol by lipase-catalyzed transesterification with vinyl 3-(4-trifluoromethylphenyl)propanoate afforded an enantiomerically pure primary alcohol. The versatility of this approach is shown in the asymmetric synthesis of 5,6-dehydrosenedigitalene (R)-1.
