A convergent synthesis of trisaccharides with α-Neu5Ac-(2 → 3)-β-D- Gal-(1 → 4)-β-D-GlcNAc and α-Neu5Ac-(2 → 3)-β-D-Gal-(1 → 3)-α-D-GalNAc sequences

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 (
