A total synthesis of the fostriecin has been achieved in 24 steps from enyne 11. The lactone moiety was installed by a Leighton allylation and Grubbs ring-closing metathesis reaction. The highly reactive Z,Z,E-triene moiety was installed via a late-stage Suzuki−Miyaura cross-coupling of a remarkably stable Z-vinyl boronate. The relative and absolute stereocenters of the C-8,9,11 triol were generated
从烯炔11开始分 24 步完成了叶轮菌素的全合成。内酯部分通过 Leighton 烯丙基化和 Grubbs 闭环复分解反应安装。高反应性Z , Z , E-三烯部分是通过后期 Suzuki-Miyaura 交叉偶联的非常稳定的Z-乙烯基硼酸酯安装的。C-8,9,11 三醇的相对和绝对立体中心是通过区域和立体选择性不对称水合/氧化序列产生的。
