Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its rigid fused ring structure and defined stereochemistry make it valuable for developing potent and selective drug candidates. Commonly employed in the preparation of nootropic agents and cognitive enhancers due to its ability to influence neurotransmitter pathways. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies, helping optimize potency and metabolic stability in small molecule drug development.
