Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds such as protease inhibitors and other therapeutic agents. Its protected amine and activated aryl group allow for selective coupling reactions in peptide-like structures. Commonly employed in asymmetric synthesis where the stereochemistry is critical for biological activity. The triflate moiety enables palladium-catalyzed cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecules.
