Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of centrally acting agents. Its spirocyclic structure and nitrogen heterocycle make it valuable in medicinal chemistry for designing compounds with enhanced selectivity and bioavailability. Commonly found in research related to neurological targets, including serotonin and dopamine receptor modulators. Also employed in the preparation of novel psychoactive substances and investigational drugs for treating depression, anxiety, and cognitive disorders. Due to its rigid framework, it helps improve metabolic stability in drug candidates.
