Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with potential antiviral or central nervous system activity. Its spirocyclic structure and functional groups make it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to explore new drug candidates, especially where conformational rigidity and specific stereochemistry are required for target binding. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to its ability to mimic peptide-like structures.
