Chemoenzymatic synthesis of sulfated O-linked oligosaccharides: Epitopes for MECA-79

Sulfated oligosaccharides I, II and III, representatives of those found on L-selectin counterreceptors, have been efficiently prepared employing a combination of chemical and enzymatic synthetic methods.

A practical synthesis of β-D-GlcA-(1→3)-β-D-Gal-(1→3)-β-D-Gal-(1→4)-D- Xyl, a part of the common linkage region of a glycosaminoglycan

A practical synthesis of β-D-GlcA-(1→3)-β-D-Gal-(1→3)-β-D-Gal-(1→4)- β-D-Xyl-(1→OMe) was achieved by coupling of methyl 2,3,4-tri-O-acetyl-α-D-glucopyranosyluronate trichloroacetimidate with a trisaccharide acceptor. The trisaccharide acceptor was obtained by condensation of 3-O-allyl-2,4,6-tri-O-benzoyl-β-D-galactopyranosyl-(1→3)-2,4,6- tri-O-benzoyl-α-D-galactopyranosyl trichloroacetimidate with methyl 2,3-di-O-benzoyl-β-D-xylopyranoside, followed by deallylation. The β-(1→3)-linked disaccharide was prepared readily with p-methoxyphenyl 3-O-allyl-2,4,6-tri-O-benzoyl-β-D-galactopyranoside as the key synthon. The α-(1→3)-linkage was formed in considerable amount with galactose mono- and disaccharide trichloroacetimidate donors with C-2 neighboring group participation.
