A stereoselective synthesis of the C8–C19 segment of cruentarens A and B, cytotoxic natural products, has been accomplished. The key steps involve a stereoselective radical cyclization, stereospecific methylation of a γ, δ-epoxy acrylate, nucleophilic epoxide ring opening and a cis-Wittig olefination.
已经完成了对角质素A和B(细胞毒性天然产物)的C 8 –C 19片段的立体选择性合成。关键步骤包括立体选择性自由基环化,γ,δ-环氧丙烯酸酯的立体有择甲基化,亲核性环氧化物开环和顺式-Wittig烯化。
