Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules such as kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to the presence of both protected amine and carbonyl functionalities. Also utilized in the preparation of pyridone and piperidone derivatives, which are important scaffolds in drug discovery programs targeting central nervous system disorders and cancer.
