Structural and Hydrogen Bonding Studies on β-Lactamase Inhibitor Penicillins by PMR Spectroscopy: Part I - Structures of Cloxacillin and Dicloxacillin Sulphoxides

Structural characterization of cloxacillin and dicloxacillin sulphoxides prepared in our laboratory indicates the S-configuration mainly as revealed by Nuclear Overhauser Enhancement (NOE) measurements, hydrogen bonding and aromatic solvent induced shift studies, etc.An interesting method of characterization of S-sulphoxides is based on the association of dimethyl sulphoxide with cloxacillin and dicloxacillin sulphoxides.
