  Synthetic studies on glycosphingolipids from the Protostomia phyla: syntheses of arthro-series glycosphingolipids

  摘要：

  Glycosphingolipids isolated from larvae of the green-bottle fly, Lucilia caesar. have quite unique structures containing GlcNAcbeta-(1-->3)-Man and GalNAcbeta-(1-->4)-GlcNAcbeta-(1-->3)-Man. We have synthesized two glycosphingolipids, beta-D-GlcNAcp-(1--> 3)-beta-D-Manp-(1-->4)-beta-D-Glcp-(1-->1)-Cer and beta-D-GalNAcp-(1-->4)-beta-D-GlcNAcp-(1-->3)-beta-D-Manp-(1-->4)-beta-D-Glcp-(1--> 1)-Cer. A key reaction in the synthetic sequence is the application of the intramolecular aglycon delivery (IAD) approach for the synthesis of the beta-mannopyranosidic linkages.
