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 R1 and R2 independently represents hydrogen or a lower alkyl group having 1-4 carbon atoms, or R1 and R2 are linked together to form an alicyclic structure having 4-7 carbon atoms, excluding the case where both R1 and R2 are 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.
一种生产 2-烷基半胱氨酰胺的工艺,包括水解通式(2)代表的 4-烷基噻唑啉-4-甲酰胺或其盐:
其中 R 代表具有 1-4 个碳原子的低级烷基;R1 和 R2 各自独立地代表氢或具有 1-4 个碳原子的低级烷基,或 R1 和 R2 连接在一起以形成具有 4-7 个碳原子的脂环结构(R1 和 R2 均为氢的情况除外),从而得到通式(1)代表的 2-烷基半胱氨酰胺或其盐
其中 R 代表具有 1-4 个碳原子的低级烷基。
具有立体选择性水解 2-烷基-L-半胱酰胺活性的微生物细胞或其处理产物可作用于通式(1)所代表的化合物,生成 2-烷基-L-半胱氨酸。
