The first total synthesis of aspinolide A has been achieved using ring-closing metathesis as a key step. The stereogenic centers were generated by means of hydrolytic kinetic resolution (HKR) of racemic epoxides. 相似文献

An efficient total synthesis of decarestrictine J has been achieved using ring-closing metathesis and Yamaguchi esterification as key steps. The stereogenic centres were generated by means of iterative hydrolytic kinetic resolution (HKR) of racemic epoxides. 相似文献

We have achieved the synthesis of Z-isomer of phomolide B during our investigation toward the effect of protecting group on the outcome of ring-closing metathesis reaction. The other key reactions involved are cis-selective partial hydrogenation, Sharpless asymmetric epoxidation, Yamaguchi esterification, and following 12 longest linear sequence with 18.5% overall yield starting from a known intermediate 20. 相似文献

A convergent and stereoselective total synthesis of decarestrictine I, a polyketide natural product, is described. Both acid and alcohol fragments were prepared from the readily available L ‐malic acid via Still? Gennari olefination and Sharpless asymmetric epoxidation. The Steglich esterification and ring‐closing metathesis (RCM) are employed to combine both acid and alcohol fragments. 相似文献
