Cu(II) nitrate impregnated zeolite has been used as an efficient supported reagent for an improved and rapid one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles in excellent yields. Condensation in the presence of supported reagents with operational simplicity, inexpensive reagents, high yield of products, and the use of non-toxic reagents makes this synthetic protocol
硝酸铜(II)浸渍的沸石已被用作有效的载体试剂,以优异的产率改进和快速地一锅合成2,4,5-三取代和1,2,4,5-四取代的咪唑。在操作简便,成本低廉的试剂,高收率的产品以及使用无毒试剂的情况下,在支持的试剂存在下进行缩合使该合成方案成为一种有吸引力的方案。
