An efficient, enantioselective total synthesis of (−)-lasubine I (1) has been achieved in an overall 8.8% yield from readily available starting materials. The important features of this approach include the creation of stereogenic centers through two sequential highly stereoselective Roush allylborations and the use of SN2 cyclization and ring-closing metathesis reactions for the construction of the
(-)-lasubine I(1)的有效,对映选择性全合成已从容易获得的起始原料中以8.8%的总收率实现。该方法的重要特征包括通过两个连续的高度立体选择性的Roush烯丙基硼酸酯形成立体异构中心,以及使用S N 2环化和闭环复分解反应来构建喹喔啉骨架。
