Chemoselective N-arylation of unprotected aminobenzamides was achieved via Cu-catalysed Chan–Evans–Lam cross-coupling with aryl boronic acids for the first time. Simple copper catalysts enable the selective arylation of amino groups in ortho/meta/para-aminobenzamides under open-flask conditions. The reactions were scalable and compatible with a wide range of functional groups.
未保护的氨基苯甲酰胺的化学选择性N-芳基化是通过Cu催化的Chan-Evans-Lam与芳基硼酸的首次交叉偶联而实现的。简单的铜催化剂可以在开瓶条件下使邻/间/对-氨基苯甲酰胺中的氨基选择性芳基化。反应是可扩展的,并且与多种官能团相容。
