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 and functional groups make it valuable in asymmetric synthesis, enabling the construction of complex drug candidates with high enantioselectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of fluorine atoms, which can enhance metabolic stability and membrane permeability. Also utilized in the preparation of peptidomimetics, where the difluoro substitution helps modulate conformational rigidity and improve pharmacokinetic properties.
