  Sulfo-Protected Hexosamine Monosaccharides:  Potentially Versatile Building Blocks for Glycosaminoglycan Synthesis

  摘要：

  [GRAPHICS]2,2,2-Trifluorodiazoethane was investigated as a reagent for sulfo group protection on hexosamine monosaccharides. The synthesis of glucosamine and galactosamine building blocks fully differentiated for glycosaminoglycan synthesis and the synthesis of glycosyl donors are described. The compatibility of trifluoroethylsulfonate under a variety of reaction conditions has also been investigated.
