As an extension of a series of dopamine D(3) receptor agonists involving FAUC 54, ex-chiral pool synthesis, and biological evaluation of 3-substituted 7-aminotetrahydroindolizines was performed. Considering the structural features of both series of enantiomers, we developed a novel alignment hypothesis for D(3) agonists, allowing for the placement of the aromatic moieties on two alternative, adjacent
