FIELD: organic chemistry. SUBSTANCE: claimed invention describes process for preparing individual stereoisomers of glutamic acid 4-alkylthio-and 4- heterylthioderivatives. Said process is based on reaction of individual stereoisomer of 4-bromoglutamic acid derivative with mercaptane salts at ratios thereof of 1:(2.5-3) in atmosphere of inert gas or nitrogen in admixture of ethanol and benzene. EFFECT: more efficient preparation process.
