Abstract

Details are reported for the synthesis of S-(1-carboxyethyl)-L-cysteine (1-CEC) and S-(1-carboxypropyl)-L-cysteine (1-CPC) from cysteine and 2-bromopropionic acid or 2-bromobutyric acid, respectively. Some analytical data and the behaviour of these two compounds on paper and ion-exchange chromatography are also reported, which allow their identification.
