The 2-naphthylmethyl (NAP) group in carbohydrate synthesis: First total synthesis of the GlyCAM-1 oligosaccharide structures

Total syntheses of the GlyCAM-1 (glycosylation-dependent cell adhesion molecule-1) oligosaccharide structures: {α-NeuAc-(2 → 3)-β-Gal-(1 → 4)-[α-Fuc-(1 → 3)]-β-(6-O-SO3Na)-GlcNAc-(1 → 6)}-[α-NeuAc-(2 → 3)-β-Gal-(1 → 3)]-α-GalNAc-OMe (1) and {α-

D-Galactose-derived D-galacturonic acid derivatives suitable as glycosyl acceptors

Allyl (1a) and benzyl (1b) β-D-galactopyranosides were converted into methyl uronates, (6a and 6b) by three different routes.The carboxyl group was introduced by Jones oxidation of suitable protected precursors and esterified directly.The chemical behaviour of 6-O-trityl-, 6-O-(4,4'-dimethoxytrityl)-, and 6-O-(2-methoxypropane-2-yl)-derivatives was investigated.The overall yields obtained were strongly influenced by the protecting groups used, in particular their stability in acidic solution.
