5-(2-Amino-2-carboxyethylthio)dopa, 2-(2-amino-2-carboxyethylthio)dopa, and 2,5-bis(2-amino-2-carboxyethylthio)dopa were synthesized from dopa and cysteine by oxidation in a neutral buffer with H2O2 in the presence of iron–EDTA complex. H2O2, iron salt, and EDTA were essential for the reaction. Ultimate oxidizing species seem to be hydroxyl and superoxide radicals.
