Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and central nervous system agents. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex nitrogen-containing heterocycles. Commonly employed in the preparation of selective receptor ligands and enzyme inhibitors, especially in research related to neurological disorders. The tert-butyl carbamate (Boc) protection allows for controlled deprotection and further functionalization in multi-step synthetic routes.
