An efficient and convenient method for the preparation of pyrimidine and quinazoline derivatives by the one-pot reaction of aromatic aldehydes, cyclic ketones and guanidine carbonate, in the presence of sodium hydroxide under solvent-free condition was reported. This method has the advantages of excellent yields, mild reaction conditions, easy work-up, and being environmentally friendly over the existing
据报道,在无溶剂条件下,在氢氧化钠存在下,通过芳族醛,环酮和碳酸胍的一锅反应,可以高效,方便地制备嘧啶和喹唑啉衍生物。与现有方法相比,该方法具有产率高,反应条件温和,易于后处理且对环境友好的优点。J.杂环化学,(2009)。
