Phosphine ligand stabilized air-stable Cu(I) complexes have been successfully used to functionalize the aromatic aminobenzoic acids in a chemoselective manner without implementing protection and deprotection strategy under mild reaction conditions. This chemoselective carbene insertion into −NH bond over −COOH and −OH bonds leads to the wide range of carboxy and hydroxy functionalized α-amino esters
