Used in pharmaceutical research as a key intermediate for synthesizing neuroactive compounds, particularly those targeting central nervous system disorders. Its chiral structure makes it valuable in developing enantioselective drugs, especially for neurological and psychiatric conditions. Commonly employed in the synthesis of pyrrolidine-based receptor modulators, including those with potential for treating pain, depression, and epilepsy. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid aromatic and heterocyclic framework.
