Abstract:
The present invention is an oxidative process for the conversion of 21-unsaturated progesterones (I) to the corresponding 3,5-secoandrost-5-one-3,17 beta -dioic acids (II) by use of either ozone or an oxidizing agent, which are useful intermediates in the production of DELTA <5>-4-aza-17-carbonyl steroids (III) which are useful in production of 5 alpha -4-aza amide (IV) pharmaceuticals.
