Abstract
A process for producing a 2-alkylcysteinamide, which comprises hydrolysis of a 4-alkylthiazolidine-4-carboxamide represented by the general formula (2) or a salt thereof: wherein R represents a lower alkyl group having 1–4 carbon atoms; and each of Rand Rindependently represents hydrogen or a lower alkyl group having 1–4 carbon atoms, or Rand Rare linked together to form an alicyclic, structure having 4–7 carbon atoms, excluding the case where both Rand Rare hydrogen, to give a 2-alkylcysteinamide represented by the general formula (1) or a salt thereof wherein R represents a lower alkyl group having 1–4 carbon atoms. Cells of a microorganism or treated products thereof having activity of stereoselective hydrolysis of a 2-alkyl-L-cysteinamide are allowed to act on the compound represented by the general formula (1) to yield a 2-alkyl-L-cysteine.
