A new synthetic route to indazolo[2,3-a]quinoxaline derivatives is described. The strategy is based on the 1,3-dipolar cycloaddition of arynes to quinoxaline–sydnone derivatives as a key step. The polyaromatic sydnones were prepared through a copper-promoted intramolecular cyclization of the C-4 position of sydnones on imines.
描述了吲唑并[2,3- a ]喹喔啉衍生物的新合成路线。该策略基于芳烃与喹喔啉-sydnone 衍生物的 1,3-偶极环加成反应,这是一个关键步骤。多环芳烃辛酮是通过铜促进辛酮在亚胺上的 C-4 位进行分子内环化而制备的。
