A three component condensation of 2-aminopyrimidines, isocyanides and 4-hydroxybenzaldehydes was studied. 3-Amino-2-(4-hydroxyphenyl)imidazo[1,2-a]pyrimidine derivatives were obtained in moderate yields. Using 4-hydroxy-3,5-dimethoxybenzaldehyde and 2-aminopyrimidine as starting materials in the condensation led to mixtures of isomeric 2- and 3-aminoimidazo[1,2-a]pyrimidines. It was demonstrated, that
研究了2-氨基嘧啶,异氰酸酯和4-羟基苯甲醛的三组分缩合反应。以中等收率获得了3-氨基-2-(4-羟基苯基)咪唑并[1,2- a ]嘧啶衍生物。使用4-羟基-3,5-二甲氧基苯甲醛和2-氨基嘧啶作为缩合反应的起始原料,得到异构的2-氨基和3-氨基咪唑并[1,2- a ]嘧啶的混合物。已经证明,该反应的区域特异性主要由嘧啶核上的取代基的空间位阻和相应醛的羰基活性定义。
