## Abstract Verbenone **1** or **2** is converted in three steps to ipsdienol **9** or **10** respectively. The diastereoisomeric 2(10)βpinenβ4βols **6** and **7** (or **5** and **8**), wich have identical chirality at the carbon atoms bearing OH groups, afford ipsdienol **10** (or **9** respective
sulmnary: Lipase-catalyzed transacylation in organic media was employed to produce optically active a-hydroxy tosylate which could be readily converted to the corresponding 1,2-epoxides with high optical purity. Conventionally, access to chiral epoxides has relied mainly upon naturally existing chi
