Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors. Its stereochemistry allows for selective interactions in biological systems, making it valuable in creating enantiomerically pure drugs. Commonly employed in research settings for constructing complex molecules requiring precise spatial arrangement of functional groups. The Boc-protected amine and ester functionalities enable stepwise deprotection and coupling reactions, facilitating its incorporation into larger peptide-like structures.
