2,3-Dihydro-1H-pyrrole-2,3-diones 1a-d react with hydrazine hydrate 2 and o-phenylenediamine 4 under different conditions to yield the pyrazole-3-carboxamide derivatives 3a-d, the pyrrol-2-ones 5a-d and the quinoxaline-2-one derivatives 6a-d, respectively. Hydrolysis of the quinoxaline-2-one derivatives 6a-d gave a substituted furo[2,3-b]quinoxaline 7. The structures of the synthesized compounds were
2,3-二氢-1 H-吡咯-2,3-二酮1a-d在不同条件下与水合肼2和邻苯二胺4反应生成吡唑-3-甲酰胺衍生物3a-d,吡咯-2-分别为5a-d和喹喔啉-2-one衍生物6a-d。喹喔啉-2-酮衍生物6a-d的水解得到取代的呋喃[2,3- b ]喹喔啉7。根据分析结果和光谱数据确定合成化合物的结构。
