Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its structure allows for selective binding and modification in drug design, enhancing bioavailability and target specificity. Commonly employed in research settings for constructing complex molecules where a functionalized cyclopropane moiety is required. Also utilized in the preparation of protease inhibitors and kinase inhibitors due to its ability to mimic peptide bonds and stabilize transition states.
