An efficient, simple and one-pot synthesis of pyrimidine derivatives by a three-component reaction of ketones, triethyl orthoformate, and ammonium acetate in the presence of boron sulfuric acid as a reusable and efficient catalyst under solvent-free conditions is reported. The reusability of catalyst, simplicity of the starting materials, short reaction time, one-pot, and good yields of products are
报道了在无溶剂条件下,在硫酸硼作为可重复使用的高效催化剂存在下,通过酮、原甲酸三乙酯和乙酸铵的三组分反应,高效、简单和一锅法合成嘧啶衍生物。催化剂可重复使用、原料简单、反应时间短、一锅法、产品收率好是主要优点。
