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 and nitrogen heterocycle make it valuable for designing drug candidates with improved metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid framework that helps constrain molecular conformation. Also explored in the preparation of novel agonists or antagonists targeting neurological pathways.
