摘要

The syntheses of three trisaccharides: α-Neu5Ac-(2→ 3)-β-d-Gal-(1→ 4)-β-d-GlcNAc→ OMe, α-Neu5Ac-(2→ 3)-β-d-Gal6SO3Na-(1→ 4)-β-d-GlcNAc→ OMe, and α-Neu5Ac-(2→ 3)- β-d-Gal-(1→ 3)-α-d-GalNAc→ OBn were accomplished by using either methyl (phenyl 5- acetamido-4, 7, 8, 9-tetra-O-acetyl-3, 5-dideoxy-2-thio-β-d-glycero-d-galacto-2- nonulopyranoside) onate or methyl (phenyl N-acetyl-5-acetamido-4, 7, 8, 9-tetra-O-acetyl- ...
