Abstract:	Stereoselective syntheses of 3-O-SO₃Na-β-Gal-(1 → 4)-β-GlcNAc-(1 → 3)-β-Gal-(1 → 4)-GlcNAc-β-OBn (15) and 3-O-SO₃Na-β-Gal-(1 → 3)-β-GlcNAc-(1 → 3)-β-Gal-(1 → 3)-β-GlcNAc-(1 → 3)-β-Gal-(1 → 4)-Glc-β-OBn (25) were accomplished through the use of two novel glycosyl donors, namely, ethyl Full-size image (8) and ethyl Full-size image (18).

Keywords:	3-O-Sialyl Lewis^x 3-O-Sialyl Lewis^a 3-O-Sulfo Lewis^x 3-O-Sulfo Lewis^a Sialyltransferases Sulfotransferases Fucosyltransferases
