We developed a novel method for synthesizing seven-membered ring carbocycles via a palladium-catalyzed intramolecular allylic alkylation?isomerization?Cope rearrangement cascade. Using easily available lactone derivatives as substrates, the target cascade reaction proceeded in the presence of 5 mol-% of Pd(dba)2 and 6 mol-% of 1,3-diphenylphosphinopropane (dppp) in THF, affording a series of seven-membered ring carbocycles in 59?88 % yield (11 examples). DFT calculations suggested that, in addition to the reaction cascade including the cis-divinylcyclopropane Cope rearrangement, there is another possible pathway based on the palladium-catalyzed intramolecular allylic substitution to construct the seven-membered ring through a retro-cyclopropanation-mediated oxidative addition.
