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

Total Synthesis and Conformational Analysis of the Antifungal Agent (-)-PF1163B
(Equation presented) (-)-PF1163B, a new macrocyclic antifungal antibiotic isolated from Streptomyces sp., has been prepared in eight steps from (S)-citronellene. The key step is a ring-closing metathesis reaction of an ester and amide derivative obtained from a substituted N-methyl-L-tyrosine.
