Copper-catalyzed rearrangement of vinyl oxiranes

A novel copper-catalyzed vinyl oxirane ring expansion protocol has been developed. A wide range of vinyl oxiranes can be rearranged to 2,5-dihydrofurans in excellent yields in the presence of electrophilic copper(II) acetylacetonate catalysts. Regioisomeric vinyl oxiranes can be converted to a single dihydrofuran product using these conditions. This method uses low catalyst loadings (0.5-5 mol %), has good tolerance of substitution patterns, and can be done in the absence of solvent. Copyright

NOVEL REDUCTION OF α-BROMO-α,β-UNSATURATED KETONES. SELECTIVE SYNTHESIS OF β,γ-UNSATURATED KETONES

Treatment of α-bromo-α,β-unsaturated ketones or 1,1-dibromo-2-trimethylsiloxycyclopropanes with diethyl phosphite and triethylamine affords β,γ-unsaturated ketones selectively.
