Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and antiviral drugs. Its chiral structure with fluorine substitution enhances metabolic stability and bioavailability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid pyrrolidine backbone and functional handles for further derivatization. Also utilized in the preparation of enzyme inhibitors where stereochemistry and fluorination play critical roles in target binding and selectivity.
