Steric and enthalpic effects of substituents on diene moieties play a crucial role in intramolecular cycloaddition reactions. Allenyl 2-halogenated-3-vinylcyclohex-2-enyl ethers underwent a tandem [4+2] cycloaddition/aromatization reaction to afford the corresponding tetrahydro-3H-naphtho[1,8-bc]furan compound in high yield.
