Used in pharmaceutical research as a key intermediate in the synthesis of central nervous system agents, particularly serotonin and dopamine receptor modulators. Its structural features make it valuable for developing compounds with potential antidepressant, anxiolytic, or antipsychotic activity. The presence of a chiral pyrrolidine core and functionalized side chains allows for high selectivity in drug design. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and metabolic stability in neuroactive drugs.
