Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and functional groups make it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in the preparation of central nervous system agents and enzyme inhibitors due to its conformational rigidity and ability to mimic peptide-like structures. Also utilized in research settings for scaffold diversification in combinatorial chemistry and structure-activity relationship (SAR) studies.
