Process for the preparation of 3,20-dioxo-pregn-4-ene and/or 3,20-dioxo-pregna-1,4-diene |
| abstract |
The conversion of certain steroid compounds with a 20-amino group to the corresponding 20-oxo derivatives is described by reaction of the steroidamine with 3,5-disubstituted o-quinone to form a steroid-anil compound and its subsequent hydrolysis to progesterone and / or dehydroesterone. |
