  Synthesis of a Forssman antigen derivative for use in a conjugate vaccine

  摘要：

  The total chemical synthesis of a Forssman antigen analog is described. The pentasaccharide contains a functionalized tether which should facilitate future conjugation with immunogenic proteins. We found that the total synthesis can be efficiently achieved by following a convergent 2+3 strategy, and using N-Troc protected GalNAc thioglycoside as a donor. (C) 2011 Elsevier Ltd.
