The facile synthesis of homogeneously α, 1 → 2 interglycosidically linked fucose hexasaccharide 17 via the disaccharide methylthio donor 10 is reported. Compound 10 in turn was synthesised from a monosaccharide thiomethyl precursor in three consecutive steps. Glycosylation employing thioglycosides activated by copper bromide/tetrabutylammonium bromide proved to be selective for the formation of α-glycosidic linkages.
