fluorescence spectral studies, and fluorescence lifetime measurements, the mechanism of this novel photoinduced multistep reaction was elucidated to involve the initial intramolecular exciplex formation, followed by the intramolecular [2 + 2] photocycloaddition between the two aromatic rings and the subsequent acid-catalyzed skeletal rearrangement of the resulting cyclobutane derivative leading to the

An intramolecular [2+2] photocycloaddition between a naphthalene and a resorcinyl moiety was followed by an acid catalyzed rearrangement leading to tricyclic tetrahydrofuran derivatives. The reaction was efficient when the irradiation was carried out at 300 nm. For the first time, an extrusion of a RCOCH3 (R=H or alkyl) fragment from the tetrahydrofuran ring was observed when the tricyclic tetrahydrofuran
