Used in medicinal chemistry as a key intermediate in the synthesis of pharmacologically active compounds, particularly those targeting central nervous system disorders. Its spirocyclic structure and nitrogen-rich framework make it valuable in designing ligands for neurotransmitter receptors, including serotonin and dopamine receptors. Commonly employed in the development of small-molecule drug candidates for treating neurological conditions such as depression, anxiety, and Parkinson’s disease. Also utilized in the preparation of novel heterocyclic compounds for structure-activity relationship (SAR) studies in early-stage drug discovery.
