The stereoselective total synthesis of PF1163A

A stereoselective total synthesis of 13-membered macrocycle PF1163A, an antifungal agent, has been accomplished for the first time starting from d-xylose. This approach involves a diastereoselective allylation of lactal ether,3a reductive ring opening of tetrahydrofuran ring,3b asymmetric methylation reaction, Yamaguchi esterification, and ring closing metathesis as key steps.
