Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its spirocyclic structure contributes to conformational rigidity, making it valuable in designing potent and selective drug candidates. Commonly employed in medicinal chemistry for optimizing metabolic stability and improving binding affinity in neuroactive drugs. Also explored in the synthesis of novel antibiotics and enzyme inhibitors due to its unique heterobicyclic framework.
