One-step stereocontrolled synthesis of α-anomeric carboxylic acid esters from unprotected glycosyl donors: A water-soluble aspirin pro-drug analogue

The reaction of 2-(3-methoxypyridyl) β-D-gluco- and D-galactopyranosides with various carboxylic acids affords the corresponding α-1-esters in high yields. Aspirin can be solubilized in water as the α-D-galactopyranosyl ester.

Practical syntheses of B disaccharide and linear B type 2 trisaccharide - Non-primate epitope markers recognized by human anti-α-Gal antibodies causing hyperacute rejection of xenotransplants

Synthetic protocols are presented for the elaboration of Galα1→3GalOR and Galα1→3Galβ1→4GlcNAcOR di- and trisaccharides that use a common Gal donor/acceptor unit, and are potentially adaptable to scale-up.
