  Synthesis of building blocks of human milk oligosaccharides. Fucosylated derivatives of the lacto- and neolacto-series

  摘要：

  The synthesis of protected fucosylated derivatives of a Gal beta(1--> 3)GlcNAc and of lactosamine Galbeta(1--> 4)GlcNAc building blocks contained in human milk oligosaccharides is described. Both chemical and enzymatic methods have been exploited for selective protection of the disaccharide. Fucosylation of the appropriate derivatives allowed an easy and relatively short access to different products from common precursors. (C) 2002 Elsevier Science Ltd. All rights reserved.
