Used as an intermediate in pharmaceutical synthesis, particularly in the development of central nervous system agents. Its spirocyclic structure and protected amine functionality make it valuable for constructing complex nitrogen-containing molecules. Commonly employed in the preparation of selective receptor modulators, including those targeting serotonin and dopamine pathways. The tert-butyl carbamate (Boc) group allows for controlled deprotection during multi-step syntheses, enabling precise functionalization. Also utilized in medicinal chemistry for optimizing drug candidates due to its favorable steric and electronic properties.
