Catalytic asymmetric oxa-Michael-Michael cascade for facile construction of chiral chromans via an aminal intermediate.

Liansuo Zu1, Shilei Zhang, Hexin Xie, Wei Wang.   

Abstract

An unprecedented highly enantioselective cascade oxa-Michael-Michael reaction has been developed. The simple and practical process, efficiently catalyzed by chiral diphenylprolinol TMS ether, affords a powerful access to highly functionalized synthetically useful chiral chromans. Moreover, notably a new activation mode involving an aminal is disclosed for the first time.
