| titleOfInvention | Process for the preparation of drospirenone |
| abstract | A process is described wherein, by employing 17a-(3-hydroxypropyl) -63,7β3;15β,16β-dimethylene-5β-androstane-3β,5,17β-triol (II) as starting product, in a single stage reaction there is obtained drospirenone, (I), whereby the reaction is achieved using gaseous oxygen as the stoichiometric oxidant in the presence of a catalytic system containing (i) TEMPO or a derivative thereof, (ii) a ferric salt (Fe3+) and (iii) NaCI. The product drospirenone is a known synthetic steroid with progestogenic, antimineralocorticoid and antiandrogenic action, that is useful for preparing pharmaceutical compositions with contraceptive action. |
