Tandospirone (I), developed as an anxiolytic drug, is an aryl-piperazine compound that binds to both 5-HT1A and dopamine D4 receptors. Palladium-catalysed hydroarylation reactions of tandospirone analogues containing an oxygen bridge and 3-(trifluoromethyl)phenyl or 2,3-dichlorophenyl groups were studied in order to find a new stereoselective access to a series of new exo-aryl(hetaryl)-substituted derivatives with potential biological activity. © 2013 Institute of Chemistry, Slovak Academy of Sciences.
