## Abstract Two conformationally constrained tropane derivatives were prepared as rigid nicotinic acetylcholine receptor ligands. A palladium catalyzed intramolecular α‐arylation reaction was employed to generate the tricyclic compounds in good yields from __N__‐(bromo‐chloropyridylmethyl)‐8‐azabic
