Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and antiviral agents. Its structure enables selective modification in drug design, enhancing metabolic stability and bioavailability. Commonly employed in research settings for constructing constrained amino acid analogs, which are valuable in peptide-based drug discovery. Also utilized in asymmetric synthesis due to the cyclopropane ring’s rigidity, aiding in stereochemical control during complex molecule assembly.
