Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure contains a protected amine and an ester functionality, making it valuable in peptide-like synthesis where selective reactions are required. The cyclopropane ring introduces conformational rigidity, which can enhance binding selectivity and metabolic stability in drug candidates. Commonly employed in multi-step organic syntheses for constructing complex molecules with stereochemical control.
