Used as an intermediate in the synthesis of chiral pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its stereochemistry allows for selective reactions in asymmetric synthesis, making it valuable in creating enantiomerically pure drugs. Commonly employed in medicinal chemistry for constructing complex molecular architectures where control of three-dimensional structure is critical. Also utilized in research settings to develop new synthetic routes requiring protected amine functionalities with steric hindrance.
