A highly enantioselective and regioselective substitution reaction of the Morita–Baylis–Hillman (MBH) carbonates with nitroalkanes catalyzed by a quinidine-derived tertiary amine–thiourea catalyst has been developed. The described method, which is different from most organocatalytic allylic substitutions of the MBH adducts to date, represents a novel approach to regioselectively functionalize the MBH
已开发出一种由对苯二胺衍生的叔胺-硫脲催化剂催化的森田-贝利斯-希尔曼(MBH)碳酸酯与硝基烷烃的高度对映选择性和区域选择性取代反应。所描述的方法与迄今为止的大多数MBH加合物的有机催化烯丙基取代方法不同,代表了一种将MBH加合物区域选择性官能化的新方法。
