As part of a program to explore the structural requirement of N-glycans in the carbohydrate-mediated biological interactions, N-linked pentasaccharide core structure was stereochemically modified in terms of glycosidic linkage. Three isomers, α-D-Man-(1→3)-[α-D-Man-(1→6)]-α -D-Man-(1→4)-β-D-GlcNAc-(1-→4)-β-D-GlcNAc-L-Asn, α-D-Man-(1→3)-[α-D-Man-(1→6)]-β -D-Man-(1→4)-α-D-GlcNAc-(1→4)-β-D-GlcNAc-L-Asn, and α-D-Man-(1→3)-[α-D-man-(1→6)]-α -D-Man-(1→4)-α-D-GlcNAc-(1→4)-β-D-GlcNAc-L-Asn, were synthesized. Synthesis of the pentasaccharide with natural linkage is also described.
