  Synthesis of 2-deoxy cyclic and linear oligosaccharides by oligomerization of monomers

  摘要：

  Cyclic and linear oligosaccharides constituted with 2-deoxy sugar units are synthesized by an oligomerization reaction involving activated thioglycoside monomers, consisting of a 2-deoxy sugar unit. The oligomerization promoter plays an important role in the formation of either the cyclic- or the linear oligosaccharides. Encapsulation abilities of a 2-deoxy cyclic hexamer with p-nitrophenot, by a H-1 NMR method, showed complexation of the guest molecule with the host molecule. (C) 2008 Elsevier Ltd.
