探讨了在微波加热条件下, 芳香醛、取代苯乙酮和尿素的三组分反应在N,N-二甲基甲酰胺(DMF)中制得4,6-二芳基-3,4-二氢嘧啶-2(1H)-酮类化合物, 收率为68%~84%. 若在反应体系中加入三甲基氯硅烷, 该三组分反应则高产率(66%~87%)地生成相应的脱氢产物4,6-二芳基嘧啶-2(1H)-酮类化合物. 该反应具有反应条件温和、产物收率高、操作方便等优点, 为4,6-二芳基-嘧啶-2(1H)-酮类药物中间体的合成提供了一条全新的路线.

Under microwave irradiation, the three-component reaction of aromatic aldehydes, substituted acetophenones and urea in N,N-dimethyl formamide (DMF) resulted in 4,6-diaryl-3,4-dihydro-pyrimidin-2(1H)-ones in 68%~84% yields. In the presence of chlorotrimethylsilane, the three-component reactions gave the corresponding dehydrogenated 4,6-diarylpyrimidin- 2(1H)-ones in satisfactory yields (66%~87%). This method of microwave irradiation for the preparation of 4,6-diaryl pyrimidin-2(1H)-ones was simple, efficient and reaction time-saving.
