A facile and efficient one-pot synthesis of 1,4-disubstituted 3-amino-2-pyridone derivatives via three-component reactions of readily available alkynyl aldehydes, amines, and ethyl 2-((diphenylmethylene)amino)acetate has been developed. The alkynyl aldehyde substrates and the amine partners can be flexibly varied to achieve a range of 3-amino-2-pyridone derivatives, which could exert interesting chemical
通过容易获得的炔基醛,胺和2-(((二苯基亚甲基)氨基)乙酸乙酯的三组分反应,已经开发了一种容易且有效的一锅法合成1,4-二取代的3-氨基-2-吡啶酮衍生物。可以灵活地改变炔基醛底物和胺伙伴,以实现一系列3-氨基-2-吡啶酮衍生物,这些衍生物可以发挥令人感兴趣的化学和生物学特性。简要解释了形成3-氨基-2-吡啶酮衍生物的反应机理。
