摘要
An efficient and highly stereoselective asymmetric synthesis of C1-C9 and C9-C17 fragments of (+)-13-deoxytedanolide have been achieved. Utilization of desymmetrization technique to prepare the triol with five stereogenic centers, regioselective Sharpless asymmetric dillydroxylation, Evans' aldol reaction, chiral methylation, and Wittig olefination are highlights of the synthesis.
