Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules that target central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocycles in medicinal chemistry. The aldehyde group allows for further derivatization, such as reductive amination or condensation reactions, enabling rapid exploration of chemical space in drug discovery. Commonly employed in the preparation of potent enzyme inhibitors and receptor modulators due to its rigid scaffold and favorable steric properties.
