We report a strategy for stereoselective O-aryl-glycoside synthesis by copper-catalyzed cross-coupling of a variety of anomeric sugars and (hetero)aromatic iodides. Stereocontrol of the α/β selectivity can be successfully realized by slight structural modifications of the oxalic diamide ligands. Mechanistic studies indicated a dynamic kinetic resolution (DKR) reaction mechanism controlled by the ligand
