## Abstract Enediyne scaffolds connected by a 9,10‐anthracenediyl spacer as a redox‐active substructure with 6‐azulenyl groups as π‐electron‐accepting groups in their periphery (3a and 3b) have been prepared by a one‐pot reaction involving repeated Pd‐catalyzed alkynylation of 6‐haloazulenes 7b and
