bestows on the newglycosyldonors enhanced stability compared to their thioglycoside counterparts toward activation conditions applied for glycosyl trichloroacetimidate (TCAI) and o-alkynylbenzoate (ABz) donor. 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
