A facile and highly efficient method for the regioselective synthesis of 1,4-disubstituted 1,2,3-triazoles (β-keto 1,2,3-triazoles) in good to excellent yields from in-situ generated β-ketoazides and terminal alkynes through Cu(I) catalyzed 1,3 dipolar cycloaddition is described. This reaction proceeds smoothly either in water or in a 1:1 mixture of water and acetone at room temperature without use
一种简便高效的方法,可从原位生成的β-酮叠氮化物和端基以高收率获得优异的1,4-二取代的1,2,3-三唑(β-酮1,2,3-三唑)区域选择性合成描述了炔烃通过Cu(I)催化的1,3偶极环加成反应。该反应在室温下在水中或在水与丙酮的1:1混合物中均可平稳进行,而无需使用任何添加剂。使用MTT测定法筛选合成的化合物在A549(肺癌),HT-29(结肠癌),He La(宫颈癌)中的细胞毒性,该试验在中等剂量下表现出明显的细胞毒性。
