Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its chiral structure makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in drug efficacy. Commonly employed in the preparation of peptide mimetics and enzyme inhibitors, especially in research targeting metabolic and neurological disorders. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its constrained cyclobutyl moiety, which helps in conformational restriction of peptide chains.
