7).0(3,5)]undec-9-ene (2) affords diene 8 with a completely rearrangedhydrocarbon skeleton via the isolable intermediate 4, along with cyclopentadiene and bromobenzene. DFT calculations show that the novel tandem retro-Diels-Alder-Diels-Alder reaction with role reversal is slightly less favored than the overall single-step Coperearrangement.
