Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in the preparation of serotonin and dopamine receptor modulators. Also utilized in the creation of novel bioactive molecules for treating neurological disorders such as depression, anxiety, and schizophrenia. Its functional groups allow for easy derivatization, supporting its role in medicinal chemistry research and development.
