2-Bromo-1-ethenyl-3,4-dihydronaphthalene (1) is subjected to palladium(0) catalysed coupling to a series of vinyl and aryl iodides via a bromozinc intermediate; the products when heated undergo 6π-electrocyclic ringclosure.

on the aromaticcore and a tethered alkyl moiety provides a straightforward approach to access these scaffolds; however, such a strategy is often hampered by the need of special reactive groups and/or less compatible cyclization conditions. It would be synthetically appealing if a common native functional group can be used as a handle to enable a general C–H annulation with diverse aromatic rings.
