7-(S)-acylaminocephalosporin sulfones and process |
| abstract |
This invention encompasses 7-(S)-acylamino-3-acetoxymethyl-3-cephem-4-carboxylic acid sulfones and the epimerization process for making them. The epimerization process empolys an organic nitrogen base reagent having a pKa between about 9.0 to about 11.5. The compounds of this invention are intermediates in the synthesis of 1-oxa-β-lactam antibiotics. |
