Herein we describe a highly chemo-, regio-, and enantioselective bromochlorination reaction of allylic alcohols, employing readily available halogen sources and a simple Schiff base as the chiral catalyst. The application of this interhalogenation reaction to a variety of substrates, the rapid enantioselective synthesis of a bromochlorinated natural product, and preliminary extension of this chemistry to
在此,我们描述了烯丙醇的高度化学、区域和对映选择性溴氯化反应,使用容易获得的卤素源和简单的希夫碱作为手性催化剂。报道了这种卤化反应在各种底物上的应用,溴氯化天然产物的快速对映选择性合成,以及这种化学在二溴化和二氯化方面的初步扩展。
