Methyl-α-d-glucopyranoside as Green Ligand for Selective Copper-Catalyzed N-Arylation

Abstract In the selective N-arylation of amines or azoles with aryl halides­, methyl-α- d -glucopyranoside ( MG ) was found to function as a green ligand of copper powder. In addition, nitrogen heterocyclic amine compounds can also undergo the N-arylation coupling with heterocyclic aryl chlorides. This process allows access to a variety of aromatic amines and aryl azoles under mild reaction conditions, has good tolerance, and proceeds in moderate to high yield.
