Supporting Information

The Supporting Information features experimental and analytical data for the synthesis of intermediates and compounds 4a, 4b, 2c–2h and 8a and 1H and 13C NMR spectra for all synthesized compounds. Procedures of photochemical experiments and their analysis are described. Detailed summaries of electronic structure calculations for two conformers (A and B) of each double bond isomer ((E)-2b and (Z)-2b), photocyclization and oxidation products 8a and 8b are given.
