Synthesis of oligosaccharides structurally related to E-selection ligands

Abstract
A tri- and a tetra-saccharide derived from methyl 3-fucosyl-β-lactoside with sulfate and N-acetylneuraminyl groups at the C-3 position of the galactose unit, analogues of sulfated Lewis X trisaccharide and sialyl Lewis X respectively, have been efficiently prepared from methyl β-lactoside in short syntheses.
