Abstract

A molecular binding event achieves a selective oxidation of C-terminal peptide acids in the presence of the electron-rich tyrosine residue. Much like a puzzle, the iron mediator easily fits to the C-terminal dicarboxylate, which behaves as a bidentate chelator for the metal center. Then, a two-electron oxidation, coupled with a rapid decarboxylation, leads to an iminium intermediate. More information can be found in the Research Article by Kevin D. Moeller, Kim S. Halskov, and Adam J. Sowers (10.1002/celc.202500142).

封面特写:多肽电化学c端脱羧的另一种机制范式(ChemElectroChem 14/2025)
在富含电子的酪氨酸残基存在的情况下,分子结合事件实现了c端肽酸的选择性氧化。很像一个谜题,铁介质很容易与c端二羧酸盐结合,它作为金属中心的双齿螯合剂。然后,一个双电子氧化,加上一个快速脱羧,得到一个含铝中间体。更多信息可以在Kevin D. Moeller, Kim S. Halskov和Adam J. Sowers的研究文章(10.1002/celc.202500142)中找到。
