Used as a chiral building block in the synthesis of peptide-based pharmaceuticals, particularly in the development of protease inhibitors. Its anthracene group enables fluorescence detection during purification and analysis, making it valuable in monitoring reaction progress and studying molecular interactions. Commonly employed in asymmetric synthesis and solid-phase peptide synthesis where stereochemical control is critical. Also serves as an intermediate in the preparation of bioactive molecules and enzyme inhibitors due to its stable chirality and functional group compatibility.
