Used as a chiral building block in the synthesis of biologically active compounds, particularly in pharmaceutical development. Its protected amine and fluorinated pyrrolidine structure make it valuable for constructing peptidomimetics and enzyme inhibitors. Commonly employed in the preparation of antiviral and antidiabetic agents where stereochemistry and fluorine substitution enhance metabolic stability and target binding. The tert-butyl carbamate (Boc) group allows for selective deprotection under mild acidic conditions, enabling stepwise assembly of complex molecules in multi-step organic syntheses.
