摘要:

       用SbCl3作催化剂, 无溶剂条件下合成了一系列二氢嘧啶酮衍生物,确定了反应的最佳条件为芳香醛、β-二羰基化合物和尿素的摩尔比为1∶1∶1.5,催化剂用量为芳香醛的10%,最佳温度为70℃。探讨了反应机理。此方法收率高、反应时间短、操作简便。

Abstract:

       We synthesized a series of 3,4-dihydropyrimidinones with SbCl3 as a catalyst and no solvent. The acquired optimal reaction conditions are molar ratio of one aromatic aldehydes, oneβ-dicarbonyl compound and one and a half urea, 0.1 mol catalyst per mol aromatic aldehydes and reaction temperature 70℃. This synthesis method has higher recovery rate and shorter reaction time and can deliver simpler operation, as compared with other traditional Biginelli reactions.
