Sažetak
Excited states of stilbenylpyrroles 1 deactivate by two photochemical processes: cis-trans isomerization and hydrogen transfer of NH to stilbene double bond. NH-transfer results in the formation of two quinone dimethane intermediates, and biradicals. Intramolecular cyclization of intermediates gives rise to polycyclic compounds: spiro-2H-pyrroles 7, pyrroloisoindoles 3 and pyrroloisoquinolines 8. Spiro-2H-pyrroles 7 rearrange on silica gel giving dihydroindoles 2. Structures of the compounds 2, 3, 8 and 9 were determined by NMR spectroscopy.
