Used in pharmaceutical synthesis as an intermediate for active pharmaceutical ingredients (APIs), particularly in the development of central nervous system (CNS) agents and antiviral drugs. Its structure supports binding to biological targets due to conformational rigidity and improved metabolic stability. Commonly employed in medicinal chemistry for optimizing drug candidates requiring enhanced bioavailability and receptor selectivity. Also utilized in the preparation of novel pyrrolidine-based compounds for research in neuropharmacology and infectious diseases.
