Used as a key intermediate in the synthesis of antiviral agents, particularly in the development of hepatitis C virus (HCV) NS5A inhibitors. Its structure enables effective binding to viral proteins, enhancing potency in inhibiting viral replication. Commonly employed in research settings for optimizing pharmacokinetic properties of drug candidates, especially those requiring improved metabolic stability and membrane permeability. The silyl protecting groups facilitate selective reactions during multi-step synthesis, making it valuable in medicinal chemistry for constructing complex molecules.
