Synthetic Studies on O-Heterocycles via Cycloadditions. Part 3. Regiochemical and Mechanistic Questions in Reactions of Polarised Diaryl Carbonyl Ylides

The unsymmetrical diaryloxiranes (9), (24), (25), and (26) undergo smooth cycloaddition with electron-deficient olefins under thermal or photochemical initiation, apparently via polarised carbonyl ylide intermediates.With unsymmetrical dipolarophiles the

Polarised Diaryl Carbonyl Ylids : The Specificity of Additions to Unsymmetric Dipolarophiles

'Push-pull' carbonyl ylids derived thermally or photochemically from oxiranes (14-16) undergo stereospecific, but uncharacteristically non-regioselective, cycloadditions with unsymmetrical electron-deficient dipolarophiles.
