摘要：

An efficient glycosylation method to synthesize 2-deoxy- O -galactosides based on a Cu(II)-catalyzed reaction without additional ligand has been developed. The glycosylation was amenable to different protected glycal donors and a wide range of acceptors including alcohols, amino acids, sugars, and phenol, and proceeds with excellent yield and high alpha -selectivity under mild conditions. The reaction proceeds readily on a gram scale, and its versatility is exemplified in the synthesis of oligosaccharides.
