This compound is widely used in peptide synthesis as a building block. It is particularly valuable for introducing the (R)-3-amino-4-(2-naphthyl)-butyric acid moiety into peptides, which can enhance their biological activity or stability. The Boc (tert-butoxycarbonyl) group serves as a protective group for the amine, ensuring selective reactions during peptide chain elongation. It is often employed in the development of pharmaceuticals, especially in the design of enzyme inhibitors or receptor modulators, where the naphthyl group can contribute to binding affinity. Additionally, it finds applications in research for studying peptide structure-activity relationships and in the production of custom peptides for biochemical studies.
