PREFERENCE FOR PHOTODISSOCIATION OVER INTERNAL -CYCLOADDITION DURING IRRADIATION OF AN UNSATURATED α,β-ENONE
Corey, E. J.,Wu, Laurence I.
, p. 663 - 664 (1994)
Irradiation of 2, its trimethylsilyl ether or acetate ester using ultraviolet light of wavelength > 290 nm results not in internal olefin-α,β-enone cycloaddition, but exclusively in photodissociation either of the intercyclic bond (for 2 or the TMS ether)
