2-ALKYLCYSTEINAMIDE OR SALT THEREOF, PROCESS FOR PRODUCING THESE, AND USE OF THESE

摘要

A process for producing a 2-alkylcysteinamide represented by the general formula (1) or a salt thereof, which comprises hydrolyzing a 4-alkylthiazolidine-4-carboxamide represented by the general formula (2) or a salt thereof. (In the general formula (1), R represents C1-4 alkyl.) (In the general formula (2), R represents C1-4 alkyl; and R1 and R2 each independently represents hydrogen or C1-4 alkyl or R1 is bonded to R2 to form a C4-7 alicyclic structure, provided that not both of R1 and R2 are hydrogen.) Either cells of a microorganism having the ability to stereoselectively hydrolyzing a 2-alkyl-L-cysteinamide or a substance obtained by treating the cells is caused to act on the compound of the general formula (1) to yield a 2-alkyl-L-cysteine.
