method for copper-catalyzed, aminoquinoline-assisted amination of β-C(sp(2))-H bonds of benzoic acid derivatives is reported. The reaction employs Cu(OAc)2 or (CuOH)2CO3 catalysts, an amine coupling partner, and oxygen from air as a terminal oxidant. Exceptionally high generality with respect to amine coupling partners is observed. Specifically, primary and secondary aliphatic and aromatic amines, heterocycles
报道了一种操作简单且通用的方法,用于铜催化、氨基喹啉辅助苯甲酸衍生物的 β-C(sp(2))-H 键胺化。该反应使用 Cu(OAc)2 或 (CuOH)2CO3 催化剂、胺偶联伙伴和来自空气的氧作为末端氧化剂。观察到关于胺偶联伙伴的异常高的通用性。具体而言,伯胺和仲脂肪族和芳族胺、杂环(例如吲哚、吡唑和咔唑)、磺酰胺以及缺电子的芳族和杂芳族胺是有效的偶联组分。
