Sialylation using N-glycolylneuraminyl phosphite donors to synthesize Neu5Gc-containing glycans

Efficient sialylations using N-glycolylneuraminic acid (Neu5Gc) phosphite donors having an acetyl or benzyl group on the glycolyl moiety are described in the synthesis of Neu5Gc-containing glycans. Both phosphite donors 1 and 2 were readily coupled with p

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

The spacer-armed trisaccharide, Neu5Gc-α-(2→3′)-lactosamine 3-aminopropyl glycoside, was synthesized by regio- and stereoselective sialylation of the suitably protected triol acceptor, 3-trifluoroacetamidopropyl 2-acetamido-3,6-di-O-benzyl-2-deoxy-4-O-(6-O-benzyl-β-D- galactopyranosyl)-β-D-glucopyranoside, with the donor methyl [phenyl 5-acetoxyacetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-2-thio-D-glycero- α,β-D-galacto-2-nonulopyranosid]onate. The donor was obtained, in turn, from methyl [phenyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-2-thio-D-glycero-α, β-D-galacto-2-nonulopyranosid]onate by N-tert-butoxycarbonylation of the acetamido group followed by total N- and O-deacetylation, per-O-acetylation, subsequent Boc group removal, and N-acetoxyacetylation.
