We have compared carbonyl diimidazole (CDI) and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDAC) as activating agents for the oligomerization of negatively-charged α- and β-amino acids in homogeneous aqueous solution. α-Amino acids can be oligomerized efficiently using CDI, but not by EDAC. β-Amino acids can be oligomerized efficiently using EDAC, but not by CDI. Aspartic acid, an α- and β-dicarboxylic acid is oligomerized efficiently by both reagents. These results are explained in terms of the mechanisms of the reactions, and their relevance to prebiotic chemistry is discussed.
