A copper-catalyzed arylation or alkenylation of quinoline N-oxides with aryl- or alkenylboronates, respectively, has been developed, which provides an efficient route for C2-substituted oxygenated quinolines under mild reaction conditions. The reaction shows a broad substrate scope for both quinoline N-oxides and aryl/alkenylboronates, mild reaction conditions, and high reaction efficiency. The formation
开发了铜催化的喹啉N-氧化物分别与芳基硼酸酯或烯基硼酸酯的芳基化或烯基化反应,为在温和反应条件下制备C2取代的含氧喹啉提供了有效的途径。该反应对喹啉N-氧化物和芳基/烯基硼酸酯具有广泛的底物范围,反应条件温和,反应效率高。芳基铜或烯基铜物质作为关键中间体的形成被认为参与了该反应。
