Document Type and Number:

Japanese Patent JPH0699470

Kind Code:

B2

Abstract:

The invention relates to a new process for the preparation of 21-hydroxy-20-keto-steroids from 17-(isocyano-sulfonylmethylene)-steroids whereby simultaneously an unsaturated bond is introduced between C16 and C17. Furthermore the invention relates to new intermediate compounds formed in this process nad their preparation and to the ultimately formed 21-hydroxy-20-keto-delta<1><6>-steroids, as far as these latter compounds are new.
