Synthesis and binding studies of some epibatidine analogues

A series of epibatidine analogues and their positional isomers bearing an 8-azabicyclo[3.2.1]octane moiety is described. Some of the compounds, especially those containing 8-azabicyclo[3.2.1]oct-2-ene moiety show high affinity for the nicotinic cholinergic receptor.
