A novel mechanism enabling selective peptide elongation by coupling α-amino acids over other potentially competing prebiotic amines under acidic aqueous condition is suggested. It proceeds via the generation of a carboxylic acid anhydride intermediate with subsequent intramolecular formation of the amide bond.
提出了一种新的机制,该机制通过在酸性水溶液条件下将α-氨基酸偶联到其他可能竞争的益生元胺上来实现选择性的肽延长。它通过生成羧酸酐中间体进行,随后在分子内形成酰胺键。
