A convenient one-pot, three-component reaction of aromatic aldehydes, 6-amino-1,3-dimethyluracil and active methylene compounds in the presence of Zr(HSO4)4 as a heterogeneous catalyst, under solvent-free conditions brings a very simple and highly efficient method for the preparation of pyrimido[4,5-b]quinolines, pyrimido[5',4':5,6]pyrido[2,3- d]pyrimidines, indeno[2',1':5,6]pyrido[2,3-d]pyrimidines
芳香醛、6-氨基-1,3-二甲基尿嘧啶和活性亚甲基化合物在 Zr(HSO4)4 作为非均相催化剂的存在下,在无溶剂条件下方便的一锅三组分反应带来了非常简单的反应。制备嘧啶并[4,5-b]喹啉、嘧啶并[5',4':5,6]吡啶并[2,3-d]嘧啶、茚并[2',1':5, 6]吡啶并[2,3-d]嘧啶和一类新的嘧啶二酮衍生物,产率很高。这种方法是通用的,并提供了几个优点,例如简单的反应设置、非常温和的反应条件、高产率、催化剂的可回收性和环境友好。
