2-氨基-4,5-二取代烃嘧啶类衍生物的新合成方法

A New Synthesis of 2-Amino-4,5-substituted Pyrimidine Derivatives

研究了2-氨基-4,5-二烃基取代嘧啶类衍生物的一个新的简易合成方法,该方法以简单且廉价的4个芳香醛和3个脂肪醛为原料,经过四步反应得到12个2-氨基-4,5-二烃基取代嘧啶类化合物,总收率在40%～70%,经氢核磁共振(1H NMR)、碳核磁共振(13C NMR)和高效液质联用(LC-MS)对其目标产物进行表征.

In this paper,a novel synthetic method for 2-amino-4,5-substituted pyrimidine derivatives was reported,which were determined by 1H NMR,13C NMR and LC-MS techniques.began from cheap and simple four aromatic aldehydes and three aliphatic aldehydes.12 compounds of 2-amino-4,5-substituted pyrimidine derivatives were synthesized by four steps with yields of 40%～70%.The structures of terminational compounds
