Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly those targeting central nervous system disorders. Its spirocyclic structure and nitrogen-containing framework make it valuable in developing receptor ligands, especially for serotonin and dopamine receptors. It has also been explored in the design of enzyme inhibitors due to its conformational rigidity and ability to mimic peptide motifs. Additionally, derivatives of this compound are investigated for potential cognitive-enhancing and neuroprotective effects.
