Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and antiviral drugs. Its structural features, including the fluorinated pyrrolidine ring and protected amine group, make it valuable for constructing bioactive molecules with enhanced metabolic stability and target selectivity. Commonly employed in medicinal chemistry for fragment coupling in drug candidates targeting central nervous system disorders and oncology. The cis-configuration and fluorine atom contribute to improved binding affinity and pharmacokinetic properties in final drug compounds.
