Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and neurodegenerative disease treatments. Its spirocyclic structure provides conformational rigidity, enhancing selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems targeting central nervous system disorders. Also utilized in the preparation of peptidomimetics due to its ability to mimic peptide turn structures, facilitating improved bioavailability and receptor binding affinity.
