A copper-catalyzed annulation of 3-aryl-2H-azirines with 2-naphthols has been developed for the rapid assembly of C-3-naphthol-substituted benzo[e]indoles in one pot. This cascade reaction was realized through dearomatic nucleophilic ring opening of azirine, intramolecular cyclization, and oxidative cross-dehydrogenative coupling to furnish the important unreported π-expanded naphthol/benzo[e]indole
已开发出铜催化的 3-芳基-2 H-氮杂环与 2-萘酚环化,用于在一个锅中快速组装 C-3-萘酚取代的苯并 [ e ] 吲哚。这种级联反应是通过氮丙啶的脱芳亲核开环、分子内环化和氧化交叉脱氢偶联来实现的,以提供重要的未报道的 π 扩展萘酚/苯并 [ e ] 吲哚联芳基化合物。
