An efficient synthesis of annulated bicyclo[2.2.2]octane having β,γ-enone chromophoric system and triplet sensitized 1,2-acyl shift rearrangement leading to the formation of angular oxa-triquinane is described. Oxidative dearomatization, intramolecular Diels–Alder reaction of 6,6-spiroepoxycyclohexa-2,4-dienone and oxa-di-π-methane reaction are the key features of our approach.
