To synthesize four stereoisomers of 2-amino-3-[(1, 2-dicarboxyethyl) sulfanyl] propanoic acid (ADC),(RS)-mercaptosuccinic acid [(RS)-MSA] was optically resolved using (1S, 2S)-2- amino-1-phenyl-1, 3-propanediol and (R)-and (S)-1-phenylethylamine as resolving agents to yield (R)-and (S)-MSA with optical purities of 100%. In addition, the racemic structures of 1- propylammonium and 1-butylammonium salts of (RS)-MSA were examined based on ...
