The relative stereochemistry of the methyl groups in 2 that would arise from the conrotately cyclization of the metastable antiparallel conformers of 1 is trans. This result is strongly suggested by PM3 calculations. Alternatively, the cis conformer 2′ is suggested to have high internal energy (ca. 40 kcal/mol) as compared with 2, which is unlikely from the point of view of the conservation of orbital symmetry theory (Woodward-Hoffmann rules){A figure is presented}.

It may be assumed that one of the possible photoproducts of 2a is 3a. However, this is not likely because Figures 1b and 2b demonstrate different behavior of 2a and 2b on vis irradiation.
