A facile novel procedure to obtain (±)-6,8-diethoxycarbonyl-6-methyl-9-H-pyrimido [4,5-b] [1,4] diazepines from 4,5-diaminopyrimidines and ethyl pyruvate is described. The structure of pyrimido [4,5-b] [1,4] diazepine derivatives for the products of this reaction was confirmed by single crystal X-ray diffraction analysis. The procedure proved to be of wide scope with reference to the substituent of
描述了一种从4,5-二氨基嘧啶和丙酮酸乙酯获得(±)-6,8-二乙氧基羰基-6-甲基-9- H-嘧啶[4,5- b ] [1,4]二氮杂pine的简便新方法。通过单晶X射线衍射分析确认了该反应产物的嘧啶基[4,5- b ] [1,4]二氮杂苯衍生物的结构。相对于起始嘧啶的取代基,该方法被证明具有广泛的应用范围。介绍了使用几种新合成的化合物作为抗癌剂和抗病毒剂进行的生物学测试结果。
