Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and protected piperidine moiety make it valuable for constructing complex heterocycles found in bioactive molecules. Commonly employed in medicinal chemistry for lead optimization, especially in programs targeting neurological disorders due to its ability to enhance metabolic stability and blood-brain barrier penetration. The Boc-protected amine allows for selective deprotection and further functionalization, enabling efficient coupling in multi-step syntheses of drug candidates.
