functionalized macrocyclic core of the novel microtubule-stabilizing agent, laulimalide, has been completed. Efficient macrolactonization was achieved by a Mitsunobu reaction, installing the sensitive (Z)-enoate, and macrocyclic stereocontrol was then exploited to introduce the methyl group and trans-epoxide.
[图:见正文]已完成3的立体选择性合成,该合成对应于新型微管稳定剂laulimalide的功能齐全的大环核心。通过Mitsunobu反应(安装敏感的(Z)-烯酸酯)可实现有效的大环内酯化,然后利用大环立体控制引入甲基和反式环氧化物。
