Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and cognitive enhancers. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for improving selectivity and metabolic stability. Commonly employed in the preparation of nootropic compounds and serotonin receptor modulators. Also utilized in research settings for building complex heterocyclic systems due to its bifunctional nitrogen atoms and ring strain characteristics.
