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 and functional groups make it valuable in constructing complex molecules with high selectivity and potency. Commonly employed in medicinal chemistry for optimizing drug candidates targeting neurological disorders, including anxiety, depression, and cognitive dysfunction. The tert-butoxycarbonyl (Boc) protecting group allows for controlled reactivity during multi-step syntheses, enabling efficient coupling and modification in peptide-like frameworks. Also utilized in research settings to explore structure-activity relationships (SAR) in novel piperidine-based therapeutics.
