Modified gluco- and galactopyranosides with sterically demanding groups in the 4-position were synthesized. Glycosylation studies of these tertiary alcohols with glycosyl trichloroacetimidates and glycosyl phosphates were performed. Despite steric hindrance the modified disaccharide moieties could be assembled in moderate yields. carbohydrates - glycosylation - steric hindrance - glycosides
