Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active molecules. Its cyclopropyl and Boc-protected amino acid structure makes it valuable for peptide mimetics and drug design where conformational rigidity is required. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its stereochemical purity and ability to influence metabolic stability and binding affinity.
