Process for preparing 3'bromo-desacetoxycephalosporanic acid sulfoxide compounds |
| abstract |
An improved process for the preparation of 3'-bromo-desacetoxycephalosphoranic acid sulfoxide compounds comprising protecting the 4-carboxy group of a 3'-unsubstituted cephalosporanic acid sulfoxide by silylating in an inert anhydrous organic solvent and brominating the silylated compound in situ which 3'-bromo compounds are valuable intermediates for the preparation of therapeutically useful cephalosporanic acid compounds. |
