Herein, we report the synthesis and structure–activity relationship of a novel series of (R)-4,4-difluoropiperidine core scaffold as dopamine receptor 4 (D4) antagonists. A series of compounds from this scaffold are highly potent against the D4receptor and selective against the other dopamine receptors. In addition, we were able to confirm the active isomer as the (R)-enantiomer via an X-ray crystal structure.
