Used in pharmaceutical synthesis as a building block for drug development, particularly in the preparation of bioactive molecules and heterocyclic compounds. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for designing kinase inhibitors, CNS agents, and other therapeutic targets. The Boc-protected amine allows for selective deprotection and further functionalization in multi-step syntheses. Commonly employed in research settings for creating novel analogs in structure-activity relationship (SAR) studies.
