Synthetic Studies on O-Heterocycles via Cycloadditions. Part 3. Regiochemical and Mechanistic Questions in Reactions of Polarised Diaryl Carbonyl Ylides
Clawson, Paul,Whiting, Donald A.
, p. 1193 - 1198 (2007/10/02)
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
