摘要: 制备了一种活性炭负载硫酸催化剂(H2SO4/AC),利用傅里叶变换红外光谱仪(FT-IR)和X射线衍射仪(XRD)表征了其形貌。 在该催化剂作用下,以芳醛、尿素、环戊酮(环己酮)为原料,在无溶剂条件下经三组分一锅法反应合成了系列环戊并[d]嘧啶酮(六氢喹唑啉酮)。 该方法用于合成此两类化合物操作简单,对环境友好,具有良好的应用前景。 催化剂易于回收和循环使用,可重复使用3次,仍保持较高活性。

Abstract: An activated carbon supported sulfuric acid catalyst (H2SO4/AC) was prepared and characterized by Fourier transform infrared (FT-IR) spectrometry and X-ray diffraction (XRD). Various cyclopenta[d]pyrimidinones and hexahydroquinazolinones were synthesized by the reaction of aromatic aldehyde with urea and cyclopentone(cyclohexanone) catalyzed by H2SO4/AC in the absence of solvent. This method is simple and environmentally benign. The catalyst can be easily recovered and its activity maintains after being reused for 3 times.

Key words: Activated carbon supported sulfuric acid, Cyclopenta[d]pyrimidinones, Hexahydroquinazolinones, Multicomponent reactions
