  A simple and versatile glycosylation method with both armed and disarmed glycosyl ynenoates as donors is developed. Employing a gold(I) complex as catalyst with or without the assistance of TfOH, the scope of the present glycosylation protocol is very wide. The utility of the present ynenoate donors is demonstrated in the efficient synthesis of oligosaccharides via the latent-active strategy and the

Thus, MPEPs can also be utilized in the selective one-pot glycosylation strategy, as exemplified by the syntheses of oligosaccharides via successive glycosylations with glycosyl TCAI, ABz, and

  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.
