Carbohydrate Research | 2011

Syntheses and NMR characterizations of epimeric 4-deoxy-4-fluoro carbohydrates

Witold Subotkowski; Dirk Friedrich; Franz J. Weiberth

The synthesis and NMR characterizations of 1,2,3,6-tetra-O-benzoyl-4-deoxy-4-fluoro-β-d-galactopyranoside, the 4-deoxy-4-fluoro epimer of an intermediate in the synthesis of a drug substance, needed for use as a potential impurity standard and to confirm the stereoselectivity of a key fluorination step, are described.
