Investigation of conformationally restricted benzamide bioisosteres led to the chiral phenyltetrahydropyrimidine derivative ent2a (FAUC 312) displaying strong and highly selectivedopamineD4 receptor binding (K(i(high))=1.5 nM). Mitogenesis experiments indicated 83% ligand efficacy when compared to the unselective agonist quinpirole. The target compounds of type 2 and 3 were synthesized in enantiopure
