Highly Substituted Cyclohexenes via Phosphine-Catalyzed [4+2] Annulation of Electron-deficient Dienes and Vinyl Ketones

by Junliang Zhang, Peng Chen, Junyou Zhang

Abstract

A highly efficient phosphine-catalyzed [4+2] annulation of electron-deficient diene and alkyl vinyl ketone was developed for the first time, which provides an easy access to functionalized cyclohexenes. This method has the advantages of mild reaction conditions, widely functional group tolerance, high yields and transition metal free.
