AN EFFECTIVE SYNTHESIS OF α-GLYCOSIDES OF N-ACETYLNEURAMINIC ACID DERIVATIVES BY USE OF 2-DEOXY-2β-HALO-3β-HYDROXY-4,7,8,9-TETRA-O-ACETYL-N-ACETYLNEURAMINIC ACID METHYL ESTER

Condensation of the acetyl protected 2-deoxy-2β-halo-3β-hydroxy-N-acetylneuraminic acid methyl ester with various acceptors such as properly protected glucose, galactose, and lactose derivatives in the presence of silver triflate gave the NeuAc α-glycosid
