| titleOfInvention |
New process for the preparation of 20-keto-delta16-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 chain containing a 20-keto group under the simultaneous formation of an unsaturated bond between C 16 and C 17 by reaction of 17-(isocyano-sulfonyl- methylene)-steroids with an alkylating agent to 20-isocyano-20-sulfonyl-delta"-steroids, followed by hydrolysis of these latter compounds to 20-keto-delta"-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. |
