A simple and efficient one-potsynthesis of polyfunctionalized benzenes has been developed via cyclocondensation of activated α-methylene alkenes such as vinyl malononitriles and ethyl vinyl cyanoacetates with nitroolefins using Cu(OTf)2/Et3N as a novel catalytic system.
通过使用Cu(OTf)2 / Et 3 N作为新型催化体系,将活化的α-亚甲基烯烃(如乙烯基丙二腈和乙基乙烯基氰基乙酸酯)与硝基烯烃进行环缩反应,已开发出一种简单高效的一锅多官能苯合成方法。
