Used as a key intermediate in the synthesis of bioactive molecules, particularly in pharmaceuticals targeting central nervous system disorders. Its spirocyclic structure provides rigidity and three-dimensionality, making it valuable in medicinal chemistry for improving metabolic stability and binding selectivity. Commonly employed in the development of gamma-aminobutyric acid (GABA) analogs and other neuroactive compounds. Also utilized in the preparation of novel enzyme inhibitors due to its unique ring strain and functional group arrangement.
