Abstract : In this report, we describe the synthesis of a novel library of $\alpha$7 nAChR ligands based on the modulation of the quinuclidine, quinazoline and tropane moieties. Spirane derivatives were newly synthesized under stereo specific 1,3 dipolar cylcoadditions. Only amide derivatives bonded efficiently to the receptor with Ki measured between 14 and 133 nM. The best fluorinated candidate was selected and radiolabeled. The potent [$^{18}$F]4 PET tracer was evaluated in rats and its brain accumulation quantified.
