Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and antiviral drugs. Its structural features allow for high enantioselectivity and binding affinity in biological systems. Commonly employed in medicinal chemistry for constructing complex molecules where stereochemical control is critical. Also utilized in asymmetric synthesis and catalysis due to the stability of the tert-butyl carbamate-protected amine group, enabling selective transformations in multi-step reactions.
