Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure allows for selective protection of functional groups during multi-step organic reactions, making it valuable in peptide and heterocyclic chemistry. Commonly employed in medicinal chemistry for building complex nitrogen-containing rings with controlled stereochemistry. The silyl and carbamate protecting groups enable stepwise deprotection and coupling, facilitating the assembly of advanced drug intermediates.
