Abstract

Optically active 2,6-dimethylcyclohexanone-2-carboxylate was prepared by PLE-catalyzed dealkoxycarbonylation of σ-symmetrical β-ketodiesters, which possess quartemary carbons at α- and α'-positions. Moreover, (-)-podocarpic acid was prepared in a short sequence from 2,6-dimethylcyclohexanone-2-carboxylate.
