Synthesis of Pentafluorophenyl Esters of Nitroveratryloxycarbonyl-Protected Amino Acids

[摘要]：For efficient peptide synthesis on a glass chip, 20 kinds of pentafluorophenyl (Pfp) esters of nitroveratryloxycarbonyl (NVOC)-protected amino acids were synthesized by using Pfp trifluoroacetate. Simple purification step gave moderate to high yield. The first loading time of each amino acid on glass surface was 3060 min. The UV cleavage of the NVOC group was completed within 10 minutes.
