A series of trisaccharide glycosides, Fuc-(1→ 2)-β-Gal-(1→ 3)-β-X-OMe (X= GlcNAc, Glc, 2- deoxy-Glc) related to the blood group determinant Led have been synthesised both as their α-and β-Fuc anomers together with the component disaccharide starting compounds. The conformational properties of the six trisaccharides together with their parent disaccharides have been investigated by NMR spectroscopy (proton and carbon chemical shifts and ...
