Abstract Microwave irradiation was used to accelerate the cyclocondensation of isoflavones with 2-aminoimidazole to synthesize 5,6-diphenylimidazo[1,2-a]pyrimidines. A series of 17 new compounds were characterized by Fourier transform infrared, NMR, and elemental analysis. 5-(2-Hydroxyl-4-isopropoxyphenyl)-6-phenylimidazo-[1,2-a]pyrimidine was determined by x-ray diffraction. A variety of substrates
摘要 微波辐照加速异黄酮与2-氨基咪唑环缩合反应合成5,6-二苯基咪唑并[1,2-a]嘧啶。通过傅里叶变换红外、核磁共振和元素分析对一系列 17 种新化合物进行了表征。5-(2-羟基-4-异丙氧基苯基)-6-苯基咪唑并-[1,2-a]嘧啶通过X-射线衍射测定。多种底物可以以良好的收率和纯度参与该过程,使该方法适用于药物发现中的文库合成。
