Metal-free synthesis of diverse 2-deoxy-β-N-glycosides through regio- and stereospecific aminoselenenylation of glycals

An efficient and metal-free method to access structurally diverse 2-phenylseleno-β- N -glycosides and 2-deoxy-β- N -glycosides through regio- and stereospecific aminoselenenylation of glycals with commercially available N-heterocycles was disclosed.
