| titleOfInvention | Process for the production of 3-oxo-pregn-4-ene-21,17-carbolactones by the metal-free oxidation of 17-(3-hydroxypropyl)-3,17-dihydroxyandrostanes |
| abstract | This invention relates to processes for the production of 3-oxo-pregnane-21,17-carbolactones of formula (II) as well as 3-oxo-pregn-4-ene-21,17-carbolactones of formula (III) by the metal-free oxidation of 17-(3-hydroxypropyl)-3,17-dihydroxyandrostanes of formula (I). In addition, the invention relates to the dichloromethane hemisolvate of 6β ,7β; 15β,16β-dimethylene-3-oxo-17α-pregnan-5β-ol-21,17-carbolactone (IV) as such as well as to a process for the production of drospirenone. |
