An enantioselective synthesis of the C-C segment of the novel antitumor agent laulimalide is described. The key steps involve a highly diastereoselective allylation, ring-closing olefin metathesis of a homoallylic alcohol derived acrylate ester, a stereoselective anomeric alkylation and an elaboration of an -methylene unit by a Julia olefination reaction.
描述了新型抗肿瘤药物劳利霉素C-C片段的对映选择性合成。关键步骤包括高度非对映选择性烯丙基化、由高烯丙醇衍生的丙烯酸酯的闭环烯烃复分解反应、立体选择性端基异构烷基化以及通过朱利亚烯烃化反应构建亚甲基单元。
