By a simple Diels-Alder reaction with extrusion of an arylnitrile molecule, the new 2H-pyrrolo[2,1-b][1,3,4]oxadiazine family was obtained from the corresponding 2H-imidazo[2,1-b][1,3,4]oxadiazine and dimethyl acetylenedicarboxylate in nearly quantitative yield.
通过一个简单的 Diels-Alder 反应和一个芳基腈分子的挤压,从相应的 2H-咪唑并[2,1-b][1,3,4]恶二嗪和乙炔二甲酸二甲酯中得到了新的 2H-吡咯并[2,1-b][1,3,4]恶二嗪家族,产量接近定量。
