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 nitrile group and protected amine functionality allow for selective transformations, making it valuable in peptide mimetics and drug discovery. Commonly employed in multi-step organic syntheses where stereochemical control is critical. The Boc-protected amine enables easy deprotection and further coupling reactions, facilitating its incorporation into complex molecular architectures.
