Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its stereochemistry allows for selective interactions in asymmetric synthesis, making it valuable in creating enantiomerically pure drugs. Commonly employed in the preparation of kinase inhibitors and central nervous system (CNS) therapeutics due to its structural compatibility with bioactive conformations. Also utilized in medicinal chemistry for scaffold modification to enhance metabolic stability and binding affinity.
