BOC-amino acid
BOC-amino acids are a class of compounds where the amino group (-NH2) of amino acids is protected by a tert-butoxycarbonyl (BOC) group. This protection is crucial in peptide synthesis to prevent unwanted reactions with other reagents or functional groups during the coupling steps. BOC-amino acids are synthesized by reacting the amino acid with BOC anhydride, resulting in the formation of the BOC-protected amino acid. In peptide synthesis, BOC-amino acids serve as building blocks for assembling peptides and proteins in a stepwise manner. The BOC group is selectively removed under acidic conditions (such as trifluoroacetic acid, TFA) after each coupling step, revealing the free amino group for the next coupling reaction.
