intermedia in organic chemistry. Herein, the direct amination of cyanohydrins with the partner of ammonia to synthesis N-unprotected α-aminonitriles is developed. The reaction proceeds via titanium-catalyzed cyano-borrowing reaction, which features high atom economy and simple operation. A broad range of ketone or aldehyde cyanohydrins was tolerated with ammonia, and the N-unprotected α-aminonitriles were

氨基腈是
天然产物中的重要组成部分,也是有机
化学中的重要中间介质。本文中,开发了
氰醇与
氨的伙伴直接胺化以合成N-未保护的α-
氨基腈。该反应通过
钛催化的
氰基借位反应进行,该反应具有较高的原子经济性和操作简单的特点。
氨可耐受各种酮或醛
氰醇,并且在温和的反应条件下以中等至高收率合成了N-未保护的α-
氨基腈。
