Used in pharmaceutical synthesis as a key intermediate for developing biologically active compounds, particularly in the production of neuroactive drugs and enzyme inhibitors. Its rigid bicyclic structure with fluorine substitution enhances metabolic stability and binding selectivity, making it valuable in medicinal chemistry for optimizing drug candidates targeting central nervous system disorders. Also employed in the design of novel antiviral and anticancer agents due to its ability to modulate peptide-like structures and improve pharmacokinetic properties.
