Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals targeting central nervous system disorders. Its structural features, including the protected amine and carboxylate groups, allow for selective modifications in multi-step syntheses. The presence of multiple stereocenters makes it valuable for constructing enantiomerically pure drugs, especially those requiring high selectivity for receptor targets. Commonly employed in the preparation of protease inhibitors and neuromodulatory agents.
