It′s a cinch! The title reaction with azomethine imines 1 uses an operationally simple procedure, based on the combination of the bromide salt of cinchona alkaloids (3) and KOH. The procedure is reliable and general. Trifluoromethyl‐substituted amines can be accessed by a two‐step deprotection of the product (S)‐2.
c!基于金鸡纳生物碱(3)的溴化物盐和KOH的组合,使用偶氮甲亚胺1的标题反应使用操作简单的程序。该程序是可靠且通用的。可通过产品(S)-2的两步脱保护来获得三氟甲基取代的胺。
