Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and protected amine group make it valuable in medicinal chemistry for constructing complex molecules with improved metabolic stability and selectivity. Commonly employed in the preparation of bioactive molecules targeting neurological disorders, including potential applications in antidepressant and antipsychotic drug research. The tert-butyl carbamate (Boc) group allows for controlled deprotection during multi-step syntheses, enabling precise functionalization of the nitrogen center.
