α-hydroxycarboxylic acid anilides via copper-catalyzed chemoselective C–N coupling reactions of α-hydroxyamides and arylhalides is described. This highly selective N-arylation process demonstrates wide substrate scope, cost savings and easy operation. In addition, the chirality of l-3-phenyllactamide is preserved during the reaction. The synthesis of highly important α-hydroxycarboxylic acid anilides via copper-catalyzed

A flexible metal-free cascade reactioninvolving aerobic C(sp3)–H hydroxylation and decarbonylation with high regioselectivity and functional group tolerance has been established. Moreover, this indirect hydroxylation approach of N-aryl amides could enable the construction of a wide range of valuable secondary alcohols at α-position of N-aryl amides. It provides a supplementary strategy for direct
