Herein, we present a full account of our efforts to couple the northern and the southern building blocks, the synthesis of which were described in the preceding paper, along with the modifications required to ultimately lead to a successful synthesis of laulimalide. Key highlights include an exceptionally efficient and atom‐economical intramolecular ruthenium‐catalyzed alkene–alkyne coupling to build
在此,我们全面介绍了我们为结合北部和南部构建基块所做的努力,其合成在前一篇论文中进行了描述,以及最终导致成功合成月桂胺所需的修改。主要亮点包括极其有效和原子经济的分子内钌催化烯烃-炔烃偶联以构建大环,然后是由铼配合物促进的高度立体选择性的 1,3-烯丙基异构化。有趣的是,设计的合成路线还使我们能够制备具有显着细胞毒活性的天然产物类似物。我们还报告了提供更简洁的天然产物合成的第二代路线。
