The total chemical synthesis of the four well-defined chitodisaccharides is described using N-trichloroacetyl (TCA) and N-benzyloxycarbonyl (Z) as C-2 protecting groups for acetamido and free amino groups, respectively. The synthesis is carried out according to a strategy that paves way to the elaboration of various homo- and hetero-chitooligosaccharides, with perfect control of the number and the position of GIcN and GIcNAc units along the oligomer chain.
