Preparative route to N-glycolylneuraminic acid phenyl 2-thioglycoside donor and synthesis of Neu5Gc-α-(2→3′)-lactosamine 3-aminopropyl glycoside

10.1016/S0008-6215(02)00003-4

The study presents a preparative route for synthesizing N-glycolylneuraminic acid phenyl 2-thioglycoside donor and Neu5Gc-α-(2→3)-lactosamine 3-aminopropyl glycoside, a spacer-armed trisaccharide. The synthesis involved regio- and stereoselective sialylation using a protected triol acceptor and a donor compound derived from methyl [phenyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-2-thio-D-glycero-α,α-D-galacto-2-nonulopyranosid]onate. The process included several chemical transformations such as N-tert-butoxycarbonylation, N- and O-deacetylation, per-O-acetylation, Boc group removal, and N-acetoxyacetylation. The synthesized trisaccharide is significant for studying carbohydrate specificity of sialyloligosaccharides-binding lectins like selectins and siglecs, which play crucial roles in cell adhesion and as receptors for various lectins. The chemicals used in the study served as starting materials, reagents, and catalysts in the synthesis process, and their purpose was to facilitate the formation of the desired trisaccharide structure through a series of well-defined chemical reactions.
