  SYNTHESIS AND APPLICATION OF SPACER-MODIFIED L-FUCOSE ANALOGUES1

  摘要：

  Starting from 6-O-tert-butyldimethylsilyl-2,3;4,5-di-O-isopropylidenealdehydo-D-galactose (1), the carbon backbone elongated GDP-L-fucose analogue 15 bearing a chromophore tag at the end of a spacer was synthesized. Additionally, the analogues of 3-L-fucosyllactose (29) and 2'-L-fucosyllactose (36), where the fucosyl moiety is marked by a five atom alkyl chain at C-5, were prepared as labeled oligosaccharides of human milk.
