Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. 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 potent ligands for neurological receptors, including those targeted in treatments for anxiety, depression, and neurodegenerative disorders. Also utilized in medicinal chemistry research to explore structure-activity relationships in novel heterocyclic systems.
