Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) 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 enzyme inhibitors and receptor modulators, especially in research targeting neurological disorders. The tert-butoxycarbonyl (Boc) group allows for easy protection and deprotection during multi-step syntheses, enhancing its utility in drug discovery and development.
