Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with central nervous system activity. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocycles in medicinal chemistry. Commonly employed in research settings to build novel drug candidates, especially those targeting neurological disorders. Also utilized in the preparation of enzyme inhibitors due to its structural similarity to proline derivatives. Suitable for use in solid-phase and solution-phase peptide-like synthesis.
