The scope of the tungstic acid catalyzed hydrogen peroxide epoxidation of olefinic alcohols is examined, at room temperature, in buffered protic media. Epoxidation occurs with complete retention of configuration for both cis and trans alkenes. Chemoselectivity is discussed with respect to the olefinic alcohol structure and olefin substituents.
