    Chemical synthesis of pseudaminic acid is described. Starting from N-acetylglucosamine, deoxygenation and deoxyamination with stereo-inversion afforded 6-deoxy-AltdiNAc, which is the key intermediate for the biosynthesis of pseudaminic acid. Subsequently, the elongation reaction via In-mediated allylation of 6-deoxy-AltdiNAc with bromomethacrylate ester derivative followed by ozonolysis and hydrolysis

This compound was selectively glycosylated at the 3′-position by the oxazoline (7) derived from lactosamine to give the protected tetrasaccharide (8) in 52% yield. Removal of the protecting groups gave the free tetrasaccharide β-D-Galp-(1 → 4)-β-D-GlcpNAc-(13)-β-D-Galp-(1 → 4)-D-GlcpNAc (9), a β-(13) dimer of N-acetyl-lactosamine. This structure
