Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its spirocyclic structure contributes to conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in the preparation of bioactive molecules targeting neurological disorders, including potential applications in antidepressant and antipsychotic drug research. Also utilized in the creation of novel analogs for structure-activity relationship studies.
