ZnCl2-catalyzed three-component coupling reaction involving a variety of functionalized enamines, triethyl orthoformate, and ammonium acetate, which leads to the production of 4,5-disubstituted pyrimidine derivatives in a single step. The procedure can be successfully applied to the efficient synthesis of mono- and disubstituted pyrimidine derivatives, using methyl ketone derivatives instead of enamines
我们开发了ZnCl 2催化的三组分偶联反应,涉及多种官能化的烯胺,原甲酸三乙酯和乙酸铵,可在单个步骤中生产4,5-二取代的嘧啶衍生物。使用甲基酮衍生物代替烯胺,该方法可以成功地用于有效合成单取代和二取代的嘧啶衍生物。
