Notes:
The complexation of four 1,6-anhydro-β-D-hexopyranoses with europium(III) was studied in aqueous solution by natural abundance 17O NMR. The paramagnetic ion induced contact shifts of individual hydroxy and ether resonances to low frequency. A clear indication of tridentate complexes was obtained, proving the involvement of the oxygen atom of the anhydro ring in talosan and mannosan and that of the pyranose ring in glucosan.
