A process for the epoxidation of 17-oxo-15,16-methylene steroids, in particular of drospirenone precursors, comprising the use of sulfoxonium ylides, in particular of dimethylsulfoxonium methyl ylide. The process allows to prepare in good yields 17-spiro epoxides, which can be easily transformed into 17-spironolacto-steroids.

Abstract

A process for the epoxidation of 17-oxo-15,16-methylene steroids, in particular of drospirenone precursors, comprising the use of sulfoxonium ylides, in particular of dimethylsulfoxonium methyl ylide. The process allows to prepare in good yields 17-spiro epoxides, which can be easily transformed into 17-spironolacto-steroids.
