Synthesis of disaccharidic sub-units of a new series of heparin related oligosaccharides

Article abstract of DOI:10.1016/S0040-4020(99)00526-8

The chemical synthesis of disaccharides 1 and 2, useful building-blocks for the preparation of a new series of heparin related oligosaccharides containing the unusual sequence (GlcN-IdoA)(n), is described. In addition, the orthogonality of the protective groups would allow access to a wide array of differently sulfated oligosaccharides. As the simplest members of this new class of oligomer, the synthesis of sulfated disaccharides 3 and 4 fully deprotected is reported.
