Herein, we report the multicomponent synthesis of pyrido[2,3-d]pyrimidine derivatives from 6-aminouracil, aromatic aldehydes, and malononitrile in glycerol as a green solvent under microwave heating. This methodology shows several advantages: catalyst-free synthesis, up to 90% yield, operational simplicity, short reaction times, easy work-up procedure, and a greener approach compared with other methods
在此,我们报道了在微波加热下以甘油为绿色溶剂,以 6-氨基尿嘧啶、芳香醛和丙二腈为原料,合成吡啶并[2,3 - d ]嘧啶衍生物的多组分方法。与文献中报道的其他方法相比,该方法显示出几个优点:无催化剂合成、高达 90% 的产率、操作简单、反应时间短、后处理程序简单以及更环保的方法。
