A series of the title compounds (R=OMe, H, Me, Ph) were prepared and photochemical behaviors of these compounds were examined. Although most of the substrates underwent intramolecular [2+2] cycloaddition to give novel trishomocubanes upon irradiation, the phenyl derivative of Δ4 isomer gave a product via competing allylic hydrogen abstraction, as well as the cyclization product.
