Abstract
An efficient Rh(I)-NHC-pincer catalyst for the highly regioselective Meinwald rearrangement of monoalkylated epoxides into methylketones under mild conditions is presented. The nucleophilic epoxide opening is assisted by Lewis acids.
摘要
本文报道了一种高效的Rh(I)-NHC钳形催化剂，该催化剂能在温和条件下将单烷基化环氧化物高度区域选择性地进行Meinwald重排生成甲基酮。亲核性的环氧化物开环反应由路易斯酸辅助。
