BC ring-systems of taxol with different or no protecting group for the C1,C2-diol moiety have been efficiently synthesized. The eight-membered B ring is formed by a ring-closing metathesis reaction (RCM) between the C10 and C11 carbon atoms. The influence of the 1,2-diol protecting group on the RCM reaction has been studied in detail. 相似文献

Marine macrolides: an improved second-generation total synthesis of the anticancer macrolide spirastrellolide A methyl ester has been achieved. The synthesis features a uniformly high level of stereocontrol combined with more expedient fragment assembly, and demonstrates a critical dependence of the crucial macrolactonization step on the substitution pattern of the C22-C24 linker region. 相似文献

Divergent strategy in natural product synthesis allows the comprehensive synthesis of family natural products. Efficient formulation of this idea requires the biosynthetic/biosynthesis-inspired insight toward the well-orchestrated design of a pluripotent late-stage intermediate, in concomitant with the applicability of the intermediates for versatile transformations. This digest focuses on the actual applications of those strategies in natural product synthesis with an emphasis on the recipes for the choice of the common intermediates. 相似文献
