Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antidiabetic drugs. Its chiral structure with defined stereochemistry makes it valuable for constructing biologically active molecules where stereo-selectivity is critical. The tert-butyloxycarbonyl (Boc) group protects the amine during peptide coupling or other multi-step reactions, while the fluoropyrrolidine moiety enhances metabolic stability and binding affinity in final drug compounds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies and optimization of drug candidates targeting proteases and kinases.
