  Chemical Synthesis of Cyclic Galactooligofuranosides Isolated from Enzymatic Degradation Products of Cell Wall Arabinogalactan of Mycobacterium tuberculosis

  摘要：

  Synthesis of cyclic tetra-, hexa- and octasaccharides containing alternating (1 -> 5)-,beta- and (1 -> 6)-beta-galactofuranosyl linkages has been achieved by intramolecular cycloglycosylation of corresponding linear sugars and by cyclooligomerization of 1,6-linked and 1,5-linked disaccharides. In particular,cyclooligornerization of the (1 -> 6)-beta-galactofuranosyl disaccharide provides an efficient way to secure all three cyclic sugars in one operation.
