Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its stereochemistry allows for selective reactions in asymmetric synthesis, making it valuable in producing enantiomerically pure drugs. Commonly employed in the preparation of peptide mimetics and antiviral compounds, where the tert-butyl carbamate group serves as a protecting group for amines during multi-step syntheses. The chloro and ketone functionalities provide reactive handles for further chemical modifications, enabling the construction of complex molecular architectures in medicinal chemistry research.
