Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of antiviral and antidiabetic drugs. Its fluorinated pyrrolidine structure enhances metabolic stability and bioavailability, making it valuable in optimizing drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid conformation and stereochemical purity. Also utilized in the preparation of protease inhibitors and kinase inhibitors where precise stereochemistry is critical for biological activity.
