A general and efficient synthesis of imidazo[2,1-a]phthalazines by palladium- and copper-mediated coupling of N-aminoimidazoles with 2-haloaryl aldehydes with concurrent imine formation is described. This new synthesis of the imidazo[2,1-a]phthalazine ring system allows for facile introduction of different substituents around the entire core. imidazo[2,1-a]phthalazine - imine formation - CH activation
描述了通过钯和铜介导的N-氨基咪唑与2-卤代芳基醛的偶合并同时形成亚胺的一般和有效的合成咪唑并[ 2,1 - a ]酞嗪的方法。咪唑并[2,1- a ]酞嗪环系统的这种新合成方法允许在整个核心周围轻松引入不同的取代基。 咪唑并[ 2,1- a ]酞嗪-亚胺形成-CH活化-N-氨基咪唑-2-溴芳基醛
