Abstract Starting from D‐mannose, D‐galactose and D‐glucosamine hydrochloride, two disaccharide blocks were synthesized. Schmidt's inverse addition technique for trichloroacetimidate was utilized for the construction of a disaccharide with a β‐mannosidic linkage in good yield. The two disaccharides in the appropriate form were then allowed to react in the presence of N‐iodosuccinimide (NIS) and tr
