Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and functional groups make it valuable for constructing complex molecules with high selectivity and potency. Commonly employed in medicinal chemistry for designing kinase inhibitors and neuroactive compounds. The tert-butyl carbamate (Boc) group allows for easy protection of the amine during multi-step syntheses, enabling controlled reactivity and improved yield in drug manufacturing processes.
