  Synthesis of selected aminodeoxy analogues of galabiose and globotriose

  摘要：

  Six aminodeoxy 2-(trimethylsilyl)ethyl (Me3SiEt) glycoside analogues of galabiose (4'- and 6'-aminodeoxy) and globotriose (6 "-, 4 "-, 2 "-, and 6'-aminodeoxy) were synthesized by glycosylation of protected Me3SiEt galactoside and lactoside accepters with azido-substituted monosaccharide donors, followed by reduction of the azido groups and removal of the protecting groups.

• Analogues of Glycosphingolipids and Glycerolipids Suitable for Conjugation to Gold- and Amino-Functionalised Surfaces
  作者：Jörgen Ohlsson、Göran Magnusson

  DOI：10.1016/s0040-4020(00)00946-7

  日期：2000.12

  A general synthesis of analogues of natural lipids, (i.e. lactosylceramide, globotriasylceramide, and phosphatidylcholine) where one of the alkyl chains carries a terminal thiol- or carboxyl functionality, is described. The lipids were prepared by N- or O-acylation of sphingosine or monoacylglycerol derivatives. These lipids are suitable for anchoring to gold- or amino-functionalised surfaces, thus

  描述了天然脂类似物（即乳糖基神经酰胺，globoriasyl神经酰胺和磷脂酰胆碱）的类似物的一般合成，其中烷基链之一带有末端硫醇或羧基官能团。通过鞘氨醇或单酰基甘油衍生物的N-或O-酰化制备脂质。这些脂质适用于锚定在金或氨基官能化的表面，从而形成细胞膜的模拟物，用于研究蛋白质与碳水化合物的相互作用。
