Used in pharmaceutical synthesis as an intermediate for bioactive molecules, particularly in the development of central nervous system agents and receptor modulators. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex heterocycles. Commonly employed in peptide mimetics and as a building block in drug discovery programs targeting neurological disorders. Also utilized in the preparation of selective enzyme inhibitors due to its conformational rigidity and favorable pharmacokinetic properties.
