described. The L-iduronyl and D-glucuronyl disaccharides 1−3 were then prepared from these compounds, by means of efficient and regioselective protective group manipulations. These disaccharides form the basis of a combinatorial approach toward the synthesis of heparan sulfate fragments representative of the heterogeneous regions of this polysaccharide.
