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 amine functionality make it valuable in medicinal chemistry for constructing complex nitrogen-containing heterocycles. It is often employed in the preparation of selective enzyme inhibitors and receptor modulators due to its conformational rigidity and ability to enhance metabolic stability in drug candidates. Commonly utilized in research settings for optimizing lead compounds in neuropharmacology and psychotropic drug discovery.
