3-amino glycosides, the current state-of-the art suffers from limited substrate scope, low yields, long reaction times, and anomeric mixtures. This work presents a novel direct method for the synthesis of 1,3-cis-3-arylsulphonaminodeoxydisaccharides and oligosaccharides via α-selective glycosylation and hydroamination of glycal in a one-pot manner. This efficient multicomponent reaction methodology
