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.
