Crucial Role of Oxidation for the Prebiotic Peptide Elongation Promoted by Carbonyl Sulfide
European Journal of Organic Chemistry, Volume 29, Issue 1, January 12, 2026.The prebiotic activation of amino acid (AA) into peptides via N‐carboxyanhydride (NCA), promoted by carbonyl sulfide (COS), cannot proceed without an oxidizing step (enabling better leaving groups than sulfur dianion). While being efficient even at mild pH the prebiotic scope of COS promoted activation of AA, it is however limited because side ...
