Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) drugs. Its structural features enable selective binding and improved metabolic stability in active compounds. Commonly employed in the preparation of serotonin and dopamine receptor modulators due to the rigid benzofuran scaffold and stereochemical purity. Also utilized in asymmetric synthesis routes where the amine functionality allows for coupling with carbonyl or sulfonyl groups to form biologically active molecules. Preferred in drug discovery for its ability to enhance enantioselectivity and pharmacokinetic properties.
