title: An enantioselective synthesis and biobehavioral evaluation of 7-fluoro-3-(p-fluorophenyl)-2-propyltropanes.
abstract: Optically pure 7-fluorotropanes 3a-c, were synthesized as structural probes of the dopamine transporter. The synthesis of these compounds was accomplished through the asymmetric 1,3-dipolar cycloaddition reaction of the oxidopyridinium betaine 4 with the chiral dipolarophile (R)-p-tolyl vinyl sulfoxide. In the preliminary analysis, tropane 3a was found to reduce the rewarding effects of cocaine in the brain stimulation reward paradigm.
