The synthesis of polyfunctionalized 7‐amino‐5‐(4‐aroyl)‐1,3‐dimethyl‐2,4‐dioxo‐1,2,3,4,5,8‐hexahydropyrido[2,3‐d]pyrimidine‐6‐carbonitrile derivatives by a green approach was achieved via one‐pot three‐component reaction of arylglyoxals, malononitrile, and 1,3‐dimethyl‐6‐aminouracil in the presence of urea as organocatalyst in EtOH:H2O (1:1) at 60°C. This protocol provides a mild and fast procedure
多官能化7-氨基-5-(4-芳酰基)-1,3-二甲基-2,4-二氧代-1,2,3,4,5,8-六氢吡啶并[2,3- d ]嘧啶通过绿色方法通过芳基乙二醛,丙二腈和1,3-二甲基-6-氨基尿嘧啶在EtOH:H 2 O(1:1中作为有机催化剂)存在下的一锅三组分反应获得了6-腈衍生物)在60°C下。该方案提供了温和而快速的程序,以良好至优异的产率合成结构多样的双环吡啶并嘧啶。
