reactive OH-3 group and, in a second step, with the reactive OH-6 group of the central beta-D-mannopyranosyl residue within the suitably protectedtrisaccharide block beta-D-GlcpNAc-(1----4)-beta-D-Manp-(1----4)-D-GlcNAc. During these coupling steps, the alpha-glycosidic linkages of D-mannopyranosyl residues were formed without neighboring-group participation, which is only successful by use of the imidate
