Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its stereochemistry allows for selective reactions in asymmetric synthesis, making it valuable in drug discovery. Commonly employed in the preparation of intermediates for antiviral and anticancer agents. The Boc-protected amine group enables easy deprotection and further functionalization, facilitating its use in multi-step organic syntheses.
