The synthesis of the pyrrolo[2,1-a]phthalazine derivatives was performed by an efficient one-pot three-component reaction starting from phthalazine, 2-bromoacetophenones and nonsymmetrical and symmetrical acetylenic dipolarophiles in 1,2-epoxybutane as both reaction medium and HBr scavenger. The structure of the compounds was assigned by IR and NMR spectroscopy.
吡咯并 [2,1-a] 酞嗪衍生物的合成是通过高效的一锅三组分反应进行的,从酞嗪、2-溴苯乙酮和不对称和对称的炔属偶极体在 1,2-环氧丁烷中作为反应介质和HBr 清除剂。化合物的结构通过红外光谱和核磁共振光谱确定。
