  Total Synthesis of Agelagalastatin

  摘要：

  The total synthesis of agelagalastatin, an antineoplastic glycosphingolipid, has been achieved. The synthesis involved an alpha-selective glycosylation of the ceramide moiety with the trisaccharide fluoride. The trisaccharide component was constructed employing the CB glycoside method which permitted a completely alpha-stereoselective galactofuranosylation.

  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.
