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. A new and simple synthesis method of 2-amino-4,5-dihydrocarbyl substituted pyrimidine derivatives was studied in this work. The simple and cheap 4 aromatic aldehydes and 3 aliphatic aldehydes were used as raw materials to obtain 12 A total of 40% ~ 70% 2-amino-4,5-dihydrocarbyl substituted pyrimidines were synthesized and characterized by 1H NMR, 13C NMR and LC -MS) to characterize its target product.
