Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex molecules with improved metabolic stability and receptor selectivity. Commonly employed in the preparation of serotonin and dopamine modulators, it enables efficient exploration of structure-activity relationships in drug discovery programs. The tert-butyl carbamate (Boc) group allows for mild deprotection, facilitating further derivatization in multi-step syntheses.
