Used as a chiral intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure supports the formation of peptide-like frameworks with enhanced metabolic stability due to the presence of the trifluoromethyl group. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting enzymes and receptors where stereochemistry plays a critical role in activity. The Boc-protected amine allows for selective deprotection and further coupling reactions in multi-step syntheses.
