An efficient formal total synthesis of (+) cortistatins A and J has been accomplished, by exploiting a highly diastereoselective intramolecular [4+3] cycloaddition of epoxy enolsilanes as the key reaction to construct rings B and C of the cortistatins in one step.
通过利用环氧烯基硅烷的高度非对映选择性分子内[4+3]环加成反应作为关键反应,一步构建了皮质抑素的B环和C环,从而实现了(+)皮质抑素A和J的高效形式全合成。
