Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with central nervous system activity. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex heterocycles. Commonly employed in the preparation of enzyme inhibitors and receptor modulators, especially in research targeting neurological disorders. The tert-butyl carbamate (Boc) group allows for selective deprotection under mild conditions, enabling stepwise assembly of multi-step synthetic pathways. Also utilized in the design of prodrugs and in peptide mimetics due to its stability and conformational rigidity.
