Synthesis of a branched biotinylated hexasaccharide structurally related to a fragment of Candida utilis glucomannan
The paper describes the synthesis of an aminopropyl glycoside of hexasaccharide structurally related to the branched fragment of Candida utilis glucomannan, consisting of tetra-α-(1→2)-d-mannoside, the non-reducing end of which is glycosylated with α-glucopyranose and α-mannopyranose residues attached through the (1→2) and (1→3) linkages, respectively. The target structure was assembled by block synthesis with controlled α-stereoselectivity of formation of each glycosidic bond. The resulting hexasaccharide was further converted to a biotinylated conjugate, which, together with previously synthesized similar oligosaccharides, will be used to study the antigenic properties of mannans of Candida fungi.
