Abstract A rhodium-catalyzed decarbonylative cross-coupling reaction of benzoquinoline-10-carbaldehydes with arylboronic acids through chelation-assisted sp2 C−CHO bond activation has been developed. A variety of functional groups substituted phenylboronic acids or benzoquinoline-10-carbaldehydes are compatible with the reaction under the optimized reaction conditions, the corresponding 10-phenylbenzo[h]quinoline derivatives were obtained in moderate to good yields. The method affords a useful strategy for the synthesis of N-heterocyclic biaryl compounds via rhodium-catalyzed sp2 C-CHO bond activation.

铑催化芳香醛和芳基硼酸通过引导基螯合指导的CC键活化的脱羰交叉偶联反应

摘要 已经开发了铑催化的苯并喹啉-10-甲醛与芳基硼酸通过螯合辅助 sp2 C-CHO 键活化的脱羰交叉偶联反应。在优化的反应条件下,多种官能团取代的苯基硼酸或苯并喹啉-10-甲醛与反应相容,相应的10-苯基苯并[h]喹啉衍生物以中等至良好的收率获得。该方法为通过铑催化的 sp2 C-CHO 键活化合成 N-杂环联芳基化合物提供了一种有用的策略。
