首次通过Cu催化的Chan-Evans-Lam交叉偶联反应实现了未保护的氨基苯甲酰胺与芳基硼酸的化学选择性N-芳基化反应。简单的铜催化剂能够在开瓶条件下使邻/Meta/对氨基苯甲酰胺中的氨基选择性芳基化。反应是可扩展的,并且与广泛的官能团相容。
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.
