NMR studies of molybdate complexes of d-erythro-l-manno-octose and d-erythro-l-gluco-octose and their alditols Original Research Article

Different amounts and various types of bis-dinuclear tetradentate molybdate complexes of d-erythro-l-manno-octose, d-erythro-l-gluco-octose, d-erythro-l-manno-octitol and d-erythro-l-gluco-octitol were characterized by 1H and 13C NMR spectroscopy in aqueous solutions. Detailed analysis of 1H–1H coupling constants and NOEs, together with chemical shifts, allowed characterization of the different isomers of these complexes.
