A mild and atom-economic gold(I)-catalyzed glycosylation for stereoselective synthesis of 2-deoxy alpha-glycosides using bench-stable 2-deoxy S-But-3-ynyl thioglycoside donors has been described. Under optimal conditions, 2-deoxy and 2,6-dideoxy thioglycoside donors were able to react with a variety of primary, secondary, and tertiary alcohol acceptors to afford alpha-selective glycosides in good to excellent yields.
