Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its spirocyclic structure and protected amine group make it valuable in medicinal chemistry for constructing complex heterocyclic systems. The Boc-protected amine allows for selective deprotection and further functionalization, enabling efficient multi-step synthesis. Commonly employed in research settings for designing drug candidates targeting cancer, inflammation, and central nervous system disorders.
