The epoxidation of cis-2-butene-1,4-diones 4 with (aqua)(hexamethylphosphoramide)oxodiperoxomolybdenum (VI), MoO5*H2O*HMPA, occured stereospecifically to give the cis-epoxides 5, whose stereochemistry was assigned on the basis of chemical evidence and a comparision of their spectral data with those of the corresponding trans-epoxides 6, which were prepared by the epoxidation of the trans-olefins 3 with alkaline hydrogen peroxide.
