概要

• 論文の詳細を見る

• 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 H<SUB>2</SUB>O<SUB>2</SUB> in the presence of iron–EDTA complex. H<SUB>2</SUB>O<SUB>2</SUB>, iron salt, and EDTA were essential for the reaction. Ultimate oxidizing species seem to be hydroxyl and superoxide radicals.
