Conformationally restricted benzamide bioisosteres were investigated when the chiral phenyldihydroimidazole derivative 4e (FAUC 179) showed strong and highly selective dopamine D4 receptor binding (K(i)high=0.95nM). Mitogenesis experiments indicated partial agonist properties (42%). EPC syntheses of the target compounds of type 4 were performed starting from alpha-amino acids.
