Oxidation of enol esters by tert-amyl hydroperoxide, catalyzed by Mo and V compounds

Metal-Catalysed Epoxidations of Olefins with Hydroperoxides

“…Mo(VI) or V(V) (83) Similarly, steroidal enol acetates were converted to the corresponding epoxides, and hence the hydroxyketones, in essentially quantitative yield [154].…”
