    Project supported by the Natural Science Foundation of the Jiangsu Higher Education Institutions of China (No. 11KJB350005), the Presidential Foundation of Xuzhou Medical College of China (No. 2010YKJ008), the Priority Academic Program Development of Jiangsu Higher Education Institutions (PAPD), and the Natural Science Foundation of Xuzhou City (Nos. XF11C062, XZZD1055).

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.

Key words: pyrimidinone, 3,4-dihydropyrimidinone, microwave synthesis, multicomponent reaction, Biginelli reaction
