mild and efficient method for the synthesis of pyrido[3,2-d]pyrimidine derivatives via three-component domino reaction of amines, aldehydes, and terminal unactivated alkynes is described using BF3˙OEt2 as Lewis acid catalyst in one pot. The features of this procedure are mild reaction conditions, good to high yields, and shorter reaction time with operational simplicity. multicomponent reaction - BF3˙OEt2
在一个锅中使用BF 3 = OEt 2作为路易斯酸催化剂,描述了一种通过胺,醛和末端未活化炔烃的三组分多米诺反应合成温和高效的吡啶并[3,2- d ]嘧啶衍生物的方法。该方法的特点是反应条件温和,收率高至高,反应时间短且操作简便。 多组分反应- BF 3 OET 2 -吡啶并[3,2- d ]嘧啶-芳香醛-苯乙炔
