  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.
