Photoinduzierte Cycloeliminierung konjugierter 5,6-Epoxy-triene der Jononreihe
UV-irradiation (λ = 254 nm; pentane) of the epoxy-triene 3 gives the isomers 4 (35 %), 5 (40 %) and 6 (5 %). The dihydrofurane 4 is the product of a thermal electrocyclization of the ylide a. On the other hand, a undergoes fragmentation to give the carbenoids b and c. Intramolecular addition of the...
