The pyrrolo[1,2-a]quinoxaline skeleton has significant potential for many biological and optical applications. Hence, in this study, unconjugated ynone derivatives were treated with 1,2-diaminoarenes in a gold-catalyzed cyclization to give 2-(1H-pyrrol-1-yl)anilines, which are valuable starting materials, and pyrrolo[1,2-a]quinoxalines by a one-pot and single-step approach. A reaction mechanism for the formation of the pyrrolo[1,2-a]quinoxaline skeleton featuring a key gold carbene intermediate is proposed. On the other hand, the methyl group on the C-2 position of the 2-(1H-pyrrol-1-yl)anilines was oxidized by SeO₂ to give the pyrrolo[1,2-a]quinoxaline skeleton, resulting in 14 different pyrrolo[1,2-a]quinoxaline derivatives.

吡咯并[1,2-a]喹喔啉骨架在许多生物和光学应用中具有巨大的潜力。因此，在本研究中，在金催化环化中用 1,2-二氨基芳烃处理非共轭炔酮衍生物，得到 2-(1 H-吡咯-1-基)苯胺（这是有价值的起始原料）和吡咯[1,通过一锅单步方法制备2- a ]喹喔啉。提出了以关键金卡宾中间体为特征的吡咯并[1,2- a ]喹喔啉骨架形成的反应机理。另一方面，2-(1H-吡咯-1-基)苯胺的C-2位甲基被SeO ₂氧化，得到吡咯并[1,2- a ]喹喔啉骨架，得到14 种不同的吡咯并[1,2- a ]喹喔啉衍生物。
