  • Synthesis of photolabile 2-(2-nitrophenyl)propyloxycarbonyl protected amino acids
    Publication number: 20050101763
    Abstract: The 2-(2-nitrophenyl)propyloxycarbonyl (NPPOC) group has been introduced as a photolabile amino protecting group for amino acids to be used as building blocks in photolithographic solid-phase peptide synthesis. NPPOC-protected amino acids were found to be cleaved in the presence of UV light about twice as fast as the corresponding o-nitroveratryloxycarbonyl (NVOC)-protected amino acids. The protected amino acids are of particular use in the synthesis of peptide arrays.
