Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic scaffolds in medicinal chemistry. Commonly employed in the preparation of potent receptor modulators and enzyme inhibitors due to its conformational rigidity and favorable pharmacokinetic properties. Also utilized in research settings for building blocks in organic synthesis, especially in routes requiring protected amine functionalities.
