Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of optically active compounds such as protease inhibitors and other bioactive molecules. Its enantiomerically pure structure makes it valuable in asymmetric synthesis, where it helps control stereochemistry during drug development. Commonly employed in the preparation of β-amino acids and peptide mimetics due to the stability and reactivity of the cyano and carbamate functional groups. Also utilized in the construction of complex molecules in medicinal chemistry research, especially in routes requiring protection of amine functionalities with orthogonal deprotection options.
