A first asymmetric total synthesis of (-)-isoschizogamine has been accomplished. Our synthesis features the facile construction of the carbon framework of the natural product through a Wagner-Meerwein rearrangement, a tandem metathesis, a stereoselective rhodium-mediated 1,4-addition of an arylboronic acid, and a ring-closing metathesis via a hemiaminal ether.
已完成(-)-异裂石蒜碱的首次不对称全合成。我们的合成方法通过 Wagner-Meerwein 重排、串联复分解、立体选择性铑介导的芳基硼酸 1,4-加成反应和通过半缩醛醚的闭环复分解反应,轻松构建了天然产物的碳骨架。
