Abstract:
A palladium-catalyzed Catellani-type [2+2+2] annulation reaction of aryl iodides, bromothiophenes, and norbornadiene, which proceeds via a tandem Heck coupling/double C-H bond activation and retro-Diels-Alder pathway to access thiophene-fused polyaromatics, is reported. The key feature of this protocol represents a NBD/NBE retaining annulation.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
