Abstract

Glycosphingolipids isolated from larvae of the green-bottle fly, Lucilia caesar, have quite unique structures containing GlcNAcβ-(1→3)-Man and GalNAcβ-(1→4)-GlcNAcβ-(1→3)-Man. We have synthesized two glycosphingolipids, β-D-GlcNAcp-(1→3)-β-D-Manp-(1→4)-β-D-Glcp- (1→1)-Cer and β-D-GalNAcp-(1→4)-β-D-GlcNAcp-(1→3)-β-D-Manp- (1→4)-β-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 β-mannopyranosidic linkages.
