Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocycles found in bioactive molecules. Commonly employed in medicinal chemistry for optimizing drug candidates targeting neurological disorders due to its favorable steric and electronic properties. Also utilized in the preparation of enzyme inhibitors and receptor modulators where structural rigidity enhances selectivity and metabolic stability.
