  According to the present invention, it becomes possible to perform a process for converting into an α-substituted cysteine represented by general formula (1) or a salt thereof at low cost and on an industrial scale by employing a process that is routed through a compound represented by general formula (3) to a compound represented by general formula (6). Particularly, by employing a process that is routed through a compound represented by general formula (7-2), it becomes possible to detach a tert-butyl protection group in a simple manner and to produce the compound represented by general formula (1) with high purity. Furthermore, by employing a process that is routed through tert-butylthiomethanol or a process that is routed through a compound represented by general formula (9), it becomes possible to produce a compound represented by general formula (2) without generating bischloromethylether that is an oncogenic substance. In the production of an α-substituted-D-cysteine or a salt thereof, it becomes possible to perform a process for converting the compound represented by general formula (2) into a compound represented by general formula (3S) in one step by allowing an enzyme or the like to act on the compound represented by general formula (2).

  根据本发明，通过采用经由一种化合物（通式（3）表示）到一种通式（6）表示的化合物的过程，可以以低成本和工业化规模进行将其转化为通式（1）表示的α-取代半胱氨酸或其盐的过程。特别是，通过采用经由一种通式（7-2）表示的化合物的过程，可以简单地去除叔丁基保护基，并以高纯度生产通式（1）表示的化合物。此外，通过采用经由叔丁基硫代甲醇或经由一种通式（9）表示的化合物的过程，可以生产通式（2）表示的化合物，而不产生致癌物质双氯甲醚。在生产α-取代-D-半胱氨酸或其盐时，可以通过允许酶或类似物作用于通式（2）表示的化合物，一步将其转化为通式（3S）表示的化合物。
