  Trifluoroethylsulfonate protected monosaccharides in glycosylation reactions

  摘要：

  A variety of sulfo-protected monosaccharide donors and acceptors were investigated in glycosylation reactions. Trifluoro-ethylsulfonate (SO3TFE) group was compatible with a wide range of activation conditions commonly used with fluoride, imidate, and sulfide donors. In addition, the influence of a SO3TFE group, at the critical 2-position in glycosyl donor, on the stereoselectivity of the glycosylation reaction was studied. (C) 2004 Elsevier Ltd.

  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.
