Asymmetric total synthesis of nonenolide stagonolide-B has been presented in this Letter. The main highlight of our synthetic strategy is the application of hydroxynitrile lyase (ParsHNL) mediated asymmetric synthesis of cyanohydrin, Sharpless asymmetric dihydroxylation, cross metathesis (CM) reaction, stereoselective Keck allylation reaction and Yamaguchi macrolactonization at a late stage enables
该信中已经提出了壬烯醇内酯-stagonolide-B的不对称全合成。我们合成策略的主要亮点是应用羟腈裂解酶(ParsHNL)介导的氰醇不对称合成,Sharpless不对称二羟基化,交叉复分解(CM)反应,立体选择性Keck烯丙基化反应和Yamaguchi大内酯化在后期使我们能够实现合成靶分子的有效分离。
