A model study toward the total synthesis of (±)-scopadulin is described. Stereocontrolled synthesis of the A/B ring system with desired functionalities was achieved by stereoselective cyanation of a bicyclic enone with Et2AlCN, diastereoselective construction of a quaternary carbon at C-4 with LDA-BOMCl, and conversion of the cyano group into a methyl group.
描述了对(±)-scopadulin的总合成的模型研究。通过用Et 2 AlCN对双环烯酮进行立体选择性氰化,使用LDA-BOMCl在C-4处对碳进行非对映选择性构型以及将氰基转化为甲基来实现具有所需功能的A / B环系统的立体控制合成团体。
