bicyclic core. A stereoselective rearrangement–epoxidation–oxidation cascade and a chelation controlled addition to a hindered acyl furan are used to install the C3, C11, C12, and C13 oxygens. The synthesis establishes eight of the nine stereocenters present in the isobenzofuran core of the massileunicellins.
描述了一种使用环醛醇反应来组装异苯并呋喃双环核的Massileunicellins方法。立体选择性重排-环氧化-氧化级联反应以及受阻酰基呋喃中螯合剂的控制添加可用于安装C3,C11,C12和C13氧。该合成建立了存在于Massileunicellins的异苯并呋喃核心中的9个立体中心中的8个。
