A catalytic intermolecular carbon electrophile induced semipinacol rearrangement was realized and the asymmetric version was also preliminarily accomplished with 92% and 82% ee. The complex tricyclic system architecture with four continuous stereogenic centers could be achieved from simple starting materials in a single step under mild conditions.
实现了分子间碳亲电子诱导半
频哪醇重排催化反应,并初步完成了不对称版本的重排,ee值分别为92%和82%。在温和的条件下,只需一步就能从简单的起始材料制备出具有四个连续立体中心的复杂
三环体系结构。
