| titleOfInvention | New process for the preparation of 20-keto-delta-16-steroids and new intermediate compounds formed in this process |
| abstract | The invention relates to a new process for the introduction into steroids of a 17-side chains containing a 20-keto group under the simultaneously formation of an unsaturated bond between C, 6 and C 17 by reaction of 17-(isocyano- sulfonylmethylene)-steroids with an alkylating agent to 20-isocyano-20-sulfonyl-delta 16 -steroids, followed by hydrolysis of these latter compounds to 20-keto-delta 16 -steroids. The invention also relates to the intermediate compounds which are formed in this process, i.e. 20-isocyano-20-sulfonyl-delta 16 -steroids and to the ultimately formed 20- keto-delta 16 -steroids, as far as these latter compounds are new. |
