Used as a key intermediate in the synthesis of complex pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports the construction of peptidomimetics, enabling enhanced metabolic stability and improved binding affinity to target enzymes. Commonly employed in medicinal chemistry for optimizing drug candidates, especially in antiviral and anticancer research. The presence of protected functional groups allows selective modifications, making it valuable in multi-step organic syntheses.
