Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of centrally acting agents such as anticonvulsants and anxiolytics. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in the preparation of gamma-aminobutyric acid (GABA) analogs and other neuroactive compounds. Also utilized in research for novel heterocyclic systems in medicinal chemistry due to its ability to mimic bioactive molecular frameworks.
