Synthesis of new sulfonylamido-penicillanic acid sulfones inhibitors of .BETA.-lactamases.
Three new sulfonylamido-penicillanic acid sulfones have been prepared by reaction of 6-aminopenicillanic esters with the monoester or monoamide derivatives obtained in nucleophilic substitution reactions by alcohol or aniline on the carboxyl chloride function of sulfoacetic dichloride followed by oxidation.

Kinetic perspectives for the degradation of oxacillin: A penicillanic acid derivative
Oxidation of oxacillin, a penicillanic acid derivative, has been predicted by monoperiodatocuprate [MPC (III)] at 25°C with 0.10 mol dm-3 ionic strength, in an aqueous alkaline medium by UV/Visible spectrophotometric analysis, for which 1:4 stoichiometry of oxacillin: MPC (III) is visible.

Preparation of Chiral Oxoazetidinesulfinates [PDF]
Diastereomeric oxoazetidinesulfinates IV were prepared from penicillanate S,S-dioxide (Sulbactam) via sulfinic acid I and sulfinyl chlorides II. Both epimers IVa and IVb gave the same oxoazetidinesulfonate V upon oxidation.
