Synthesis and NMR characterization of the six regioisomeric monophosphates of octyl β-d-galactopyranosyl-(1→4)-2-acetamido-2-deoxy-β-d-glucopyranoside Original Research Article

All six regioisomeric monophosphates of octyl β-d-galactopyranosyl-(1→4)-2-acetamido-2-deoxy-β-d-glucopyranoside have been chemically synthesized and characterized by high-resolution 1H, 13C and 31P NMR spectroscopy. Phosphorylation causes characteristic downfield shifts of the nucleus at the substituted site in the 1H and 13C NMR signals and resulted in a unique 31P signal for each compound.
