p-Nitrobenzyloxycarbonyl (pNZ) was used as a temporary protecting group for α-amino functionalities in solid-phase peptide synthesis. The corresponding derivatives are readily synthesized solids that perform well on solid phase. The pNZ moiety is orthogonal with the most common protecting groups used in peptide chemistry, and is removed under neutral conditions in the presence of catalytic amounts
对硝基苄氧羰基 (pNZ) 在固相肽合成中用作 α-氨基官能团的临时保护基团。相应的衍生物是易于合成的固体,在固相上表现良好。pNZ 部分与肽化学中最常用的保护基团正交,并在中性条件下在催化量的酸存在下被去除。pNZ 衍生物与 Fmoc 化学的结合使用避免了与使用哌啶相关的典型副反应,例如 DKP 和天冬酰胺的形成。pNZ 的灵活性可用于制备有机小分子库。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
