A Catalytic Cross-Olefination of Diazo Compounds with Sulfoxonium Ylides

A ruthenium-catalysed cross-olefination of diazo compounds and sulfoxonium ylides is presented. Our reaction design exploits the intrinsic difference in reactivity of diazo compounds and sulfoxonium ylides as both carbene precursors and nucleophiles, which results in a highly selective reaction.

Stereospecific Epoxidation of cis-2-Butene-1,4-diones to cis-2,3-Epoxybutane-1,4-diones with Oxodiperoxomolybdenum (VI), MoO5*H2O*HMPA

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.
