The utilization of water as solvent and indium trichloride as promoter for the three-component combinatorial synthesis of a variety of bioactive pyrimidine and pyrazole derivatives (2–10) from aldehydes, 1,3-dicarbonyl compounds, and electron-rich amino heterocycles like 6-amino-1,3-dimethyl uracil and 3-methyl-1-phenyl-1H-pyrazol-5-amine catalyzed by indium trichloride under reflux has been studied
利用水作为溶剂,并使用三氯化铟作为促进剂,由醛,1,3-二羰基化合物和富含电子的氨基杂环(如6)三组分组合合成多种生物活性嘧啶和吡唑衍生物(2-10)研究了三氯化铟在回流条件下催化的-氨基-1,3-二甲基尿嘧啶和3-甲基-1-苯基-1 H-吡唑-5-胺。还合成了一类新的嘧啶衍生物(2),并通过单晶X射线分析证实了其结构。反应对环境无害,反应产物易于分离,催化剂可以回收利用,这使其成为有吸引力的合成方案。
