Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and protected amine functionalities make it valuable in medicinal chemistry for constructing complex amines and nitrogen-containing heterocycles. Commonly employed in the preparation of selective enzyme inhibitors and receptor ligands. The tert-butyl carbamate (Boc) protection allows for controlled deprotection and further functionalization in multi-step organic syntheses.
