Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in constructing complex molecules with chiral centers. Commonly employed in solid-phase peptide synthesis and medicinal chemistry for introducing constrained cyclopropyl motifs that enhance metabolic stability and binding affinity. Also utilized in the preparation of bioactive molecules where steric control and polarity are critical for activity.
