Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with potential neurological or central nervous system activity. Its spirocyclic structure and protected functional groups make it valuable in medicinal chemistry for constructing complex amines and heterocycles. Commonly employed in research settings for designing enzyme inhibitors or receptor ligands. The tert-butyl and benzyl protecting groups allow selective deprotection, enabling stepwise synthesis in multi-step organic reactions.
