Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules with central nervous system activity. Its rigid spirocyclic structure contributes to enhanced metabolic stability and selectivity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in the design of enzyme inhibitors and receptor modulators. Also utilized in the preparation of specialty compounds for research in neuropharmacology and psychotropic drug development.
