A new and facile method for stereoselective synthesis of (E)-styryl bromides by the reduction of 1,1-dibromoalkenes using LiAlH4-EtOAc (1 : 1)

摘要

A facile method for stereoselective synthesis of (E)-styryl bromides by the reduction of 1, 1-dibromoalkenes using LiAlH4-EtOAc (1: 1) is described. We believe that the present procedure is a good alternative to the Tokuda's microwave method with good stereoselectivity.
