Liquid-Phase Peptide Synthesis Enabled by Electrochemical Amide Bond Formation
摘要
Electrode reactions can use electrons as traceless and waste-free redox reagents instead of chemicals. The development of “electrochemical” amide bond formation has enabled a new liquid-phase peptide synthesis without the use of typical coupling reagents. A triphenylphosphine radical cation generated by an electrode reaction activates carboxylic acids by providing phosphonium ions to induce amide bond formation, leading to the synthesis of peptides.
