Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in the preparation of kinase inhibitors and receptor modulators. The Boc-protected amine allows for controlled deprotection and further functionalization in multi-step synthetic routes. Frequently utilized in medicinal chemistry research for optimizing lead compounds.
