A new synthetic approach to thieno[2,3-d]imidazoles is presented on the basis of the N′-(3-halothiophen-2-yl)amidine cyclization under copper-catalyzed cross-coupling. Using commercially available starting materials such as 2-aminothiophenes or their Boc-protected derivatives and copper catalysts, this method offers a convenient route to a wide range of thieno[2,3-d]imidazole derivatives, especially
基于铜催化交叉偶联下的 N'-(3-卤代噻吩-2-基)脒环化反应,提出了一种合成噻吩并[2,3-d]咪唑的新方法。使用市售的起始材料,如 2-氨基噻吩或其 Boc 保护的衍生物和铜催化剂,该方法为广泛的噻吩并 [2,3-d] 咪唑衍生物,尤其是 5-烷基取代的噻吩并[2,3-d]咪唑。
