unprecedented phenylsulfanyl group assisted generation of pyridine o-quinodimethane intermediates and their trapping by an intramolecular Diels-Alder reaction. Pharmacological characterization of some of these analogues at activating alpha3beta4 nAChRs was investigated, and constrained anabasine analogues 35 and 43 as well as constrained nicotine analogue 42 were found to exhibit moderately potent nicotinic
