Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting neurological disorders and antiviral agents. Its structure enables selective amine protection during multi-step syntheses, making it valuable in the development of protease inhibitors and kinase inhibitors. Commonly employed in medicinal chemistry for constructing constrained amino acid analogs that enhance metabolic stability and receptor selectivity. Also utilized in the preparation of prodrugs and peptide mimetics due to its favorable deprotection profile and steric properties.
