Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and protected amine functionalities make it valuable in medicinal chemistry for constructing complex heterocycles. Commonly 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. Also utilized in combinatorial chemistry for generating compound libraries aimed at discovering new therapeutic agents.
