Synthesis of 2-aminoethyl glycosides of chitooligosaccharides

2-Aminoethyl glycosides of chitotriose, chitopentaose, and chitoheptaose were synthesized. The successive extension of the oligosaccharide chain by two monosaccharide residues was carried out using a monosaccharide acceptor and a disaccharide donor, in which amino groups were protected by phthaloyl groups, benzyl moieties were used as a permanent protection for the hydroxy groups at C(3) and C(6), and acetyl or chloroacetyl groups were employed as a temporary protection for the hydroxy group at C(4).
