Used as a key chiral intermediate in the synthesis of certain pharmaceutical agents, particularly in the development of protease inhibitors and antiviral drugs. Its rigid cyclopropane structure and specific stereochemistry enhance binding selectivity to target enzymes, improving drug efficacy. The difluorophenyl group contributes to metabolic stability and membrane permeability, making it valuable in optimizing pharmacokinetic properties. Commonly employed in research and process chemistry for constructing complex bioactive molecules.
