obtain some imidazo[1,2-a]pyridines, imidazo[1,2-a]pyrimidines, imidazo[2,1-b]thiazoles and imidazo[2,1-b]benzothiazoles characterized by the presence of a phenyl moiety on the imidazole ring. In the case of thiazole and benzothiazole derivatives, unexpected by-products were isolated and their structures elucidated.
各种杂芳基胺与2-苯甲酰基-2-溴乙酸乙酯的反应用于获得一些咪唑并[1,2- a ]吡啶,咪唑并[1,2- a ]嘧啶,咪唑并[2,1- b ]噻唑和咪唑[2,1- b ]苯并噻唑的特征在于在咪唑环上存在苯基部分。对于噻唑和苯并噻唑衍生物,分离出了意外的副产物并阐明了其结构。
