Synthesis of an allergy inducing tetrasaccharide “4P-X”

4P-X (β-D-galactopyranosyl-(1?→?4)-β-D-galactopyranosyl-(1?→?6)-[β-D-galactopyranosyl-(1?→?4)]-β-D-glucopyranose) is included in galacto-oligosaccharides (GOSs) produced by β-galactosidase derived from Bacillus circulans. 4P-X has been known to induce particularly strong allergies. High purity 4P-X is essential for use as a standard to quantify the amount of 4P-X in GOSs; however, the isolation of high purity 4P-X has never been reported. In this study, we achieved the synthesis of 4P-X by a combination of organic and enzymatic chemical syntheses in a short time. This is the first report of isolated, high purity 4P-X.

A versatile strategy for the synthesis of complex type N-glycans: Synthesis of diantennary and bisected diantennary oligosaccharides1

Based on readily available glucose, 2-azido-glucose, mannose, and N- phthaloyllactosamine building blocks 5, 6, 8, and 13 a highly versatile strategy for the synthesis of complex type and bisected complex type N- glycan residues is established; this is demonstrated for the synthesis of nonasaccharide 1 and decasaccharide 2, respectively. The glucose residue g finally provides regioselective access to the 3-, 4-, and/or 6-hydroxy groups for antenna attachment, introduction of the bisecting N-acetylglucosamine residue, and epimerisation at C-2 in order to generate the required β- linked mannosyl residue c.
