  Introduction ofC-Sulfonate Groups into Disaccharide Derivatives

  摘要：

  To prepare C-sulfonate derivatives of disaccharides two different strategies were followed. Thus 6- and 6'-C-sulfocellobiosides 4 and 10-12 were prepared starting from a suitably protected cellobioside. The 6'-C-sulfoaminocellobioside 18 was prepared by construction of the molecule through a glycosylation reaction. In both cases, the synthetic pathway involves regioselective tosylation, introduction of a sulfur atom by nucleophilic displacement with potassium thioacetate and oxidation with hydrogen peroxide.
