This chemical is primarily used in the synthesis of peptides and peptidomimetics, where it serves as a protected amino acid derivative. The tert-butoxycarbonyl (Boc) group provides stability during the peptide coupling process, preventing unwanted side reactions. It is particularly valuable in solid-phase peptide synthesis (SPPS), enabling the stepwise construction of complex peptide chains. Additionally, it finds application in the development of pharmaceutical compounds, especially in the creation of protease inhibitors and other bioactive molecules. Its structural features, including the bulky tert-butyl group, help in controlling stereochemistry and enhancing the stability of intermediates during chemical transformations.
