A simple and efficient one-pot synthesis of 4-substituted-3,5-dicyano-2,6-piperidinediones was achieved in good yields via the three-component reaction of aldehyde or ketone, ethyl cyanoacetate, lithium nitride (Li 3 N) as a convenientsource of ammonia in MeOH.
通过醛或酮、氰基乙酸乙酯、氮化锂 (Li 3 N) 的三组分反应,以良好的收率实现了简单高效的一锅法合成 4-取代-3,5-二氰基-2,6-哌啶二酮作为 MeOH 中氨的方便来源。
