obtained for the glycosylation of 2-O-acetyl-protected disarmedglycosyldonors, whereas armedglycosyl trichloroacetimidates gave rise to a mixture of anomeric glycosides. Acid-sensitive nucleophiles such as Fmoc-serine tert-butyl ester or Fmoc-threonine tert-butyl ester successfully underwent the glycosylations, albeit in moderate yields, under mild conditions at room temperature.
