An efficient stereoselective total synthesis of 12-membered macrolide dendrodolide L has been achieved. The key reactions involved are Keck asymmetric allylation, Jacobsen's hydrolytic kinetic resolution, Sharpless asymmetric epoxidation, Mitsunobu reaction and ring-closing metathesis reaction.

Abstract A new synthetic route for the totalsynthesis of dendrodolide-L has been developed from known chiral epoxides. The key reactions involved in this synthesis are regioselective ring-opening of epoxide, Yamaguchi esterification and ring-closing metathesis reactions (RCM) to result the target compound.

A short and efficient method for the stereoselective synthesis of Dendrodolide L has been developed from inexpensive and commercially available starting material. This convergent synthesis utilizes Jacobsen kinetic resolution, regioselective ring-opening of epoxide and Yamaguchi macrolactonization as key steps.
