  • METHOD FOR PRODUCING a-SUBSTITUTED CYSTEINE OR SALT THEREOF OR SYNTHETIC INTERMEDIATE OF a-SUBSTITUTED CYSTEINE

    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。
  • An Improved Method for the Preparation of Protected (R)-2-Methylcysteine: Solution-Phase Synthesis of a Glutathione Analogue
    作者:Douglas Masterson、Brant Kedrowski、Amanda Blair
    DOI:10.1055/s-0030-1259021
    日期:2010.12
    A synthetic method for the preparation of (R)-2-methylcysteine that dramatically improves the overall yield of this important unnatural amino acid has been refined. The key steps in the preparation of (R)-2-methylcysteine were improved such that necessary intermediates were prepared in high yields and of sufficient purity to avoid the need for distillation or column chromatography. The (R)-2-methylcysteine was prepared (>90% ee) in appropriately protected form and used in a novel solution phase synthesis of a glutathione analogue.
