WebApr 1, 2024 · Getting a carboxylic acid to react directly with an amine is very difficult, that's why the body uses a huge ribosome to facilitate it. In a lab these couplings are also very complex, everything is protected apart from your target carb. acid and amine, which are then joined with coupling agents like DCC or HATU. WebThe overall reaction is shown below: Step 1: Amine adds on the carbonyl group, which leads to the formation of the nucleophilic addition product. Step 2: The addition product formed gives a negative charge on the oxygen atom and a positive charge on the nitrogen atom.
