Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its Boc-protected amine and carboxylic acid functionality allow for selective coupling reactions in peptide-like structures. The compound’s stereochemistry and aromatic side chain make it valuable for constructing enzyme inhibitors where specific three-dimensional orientation enhances binding affinity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies and in the preparation of intermediates for drugs targeting neurological and metabolic disorders.
