of the peptide condensation methods termed thioester method, an amino protecting group is required in the lysine side chain. In this study, to investigate the efficiency of the pyruvoyl group as an amino protecting group, we synthesized Nα-fluorenylmethoxycarbonyl (Fmoc)-Nε-pyruvoyl-lysine and introduced it into peptides and glycopeptides by the ordinary Fmoc-based solid phase peptide synthesis. The
在一种称为硫酯法的肽缩合方法中,赖氨酸侧链中需要氨基保护基。在这项研究中,为了研究丙酮酰基作为氨基保护基的效率,我们合成Ñ α -fluorenylmethoxycarbonyl羰基(Fmoc) - ñ ε -pyruvoyl赖氨酸和将其引入到由普通基于Fmoc的固相肽的肽和糖肽合成。丙酮酰肽可以通过硫酯方法与肽硫酯缩合,并且该保护基很容易通过邻苯二胺处理而除去,而没有明显的副反应。
