    Processes are described for epoxidation reactions. In particular, the process comprises the conversion of a steroid substrate having an olefinic unsaturation in the steroid nucleus to a structure comprising a 9,11-epoxy substituent by reaction of the substrate with a peroxide compound in the presence of a peroxide activator. The epoxidation processes described are conducted at relatively low hydrogen peroxide to steroid substrate ratio. Several optional process modifications are described.
