Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of protease inhibitors and other biologically active compounds. Its stereochemistry makes it valuable for constructing enantioselective drug molecules. Commonly employed in peptide mimetics and enzyme inhibitor design due to the presence of the activated carbamate and carboxylic acid functional groups. Widely applied in medicinal chemistry for developing drugs with improved metabolic stability and target specificity.
