Abstract: | The title compound 3 was isolated after pyrolysis of cis/trans- 1 at 240°, respectively of cis/trans- 8 at 156°. Thermolysis of cis/trans- 8 at 111° resulted in the deconjugated product 9 , which subsequently could be rearranged via a 1,7] H-shift preferentially into the trans-isomer of 8 . Upon heating at 250°, 3 underwent a series of pericyclic reactions to furnish 11 , whereas epi- 3 did not react under these conditions. |
