    t-Alkylation of carboxylic esters via their ketene alkyl trimethylsilyl acetals by the Friedal-Crafts reaction allows the synthesis of new highly hindered compounds. A new route using sodium amide in dimethoxyethane, for the preparation of trimethylsilylenol ethers of ketones, is described. The α-t-butylation of these compounds permits the synthesis of new crowded pentasubstituted ketones. The limits

    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。
  • Steric limits to ester alkylation; synthesis of highly hindered esters via hexamethylphosphoramide-favoured enolization
    作者:John Anthony MacPhee、Jacques-Emile Dubois

    αα-disubstituted from α-monosubstituted esters takes place in high yields and appears to be only slightly influenced by the nature of the alkylating agent (Mel, Etl, or Pril). In contrast, the formation of ααα-trisubstituted for αα-disubstituted esters appears to be sensitive to the steric nature of the ester to be alkylated. Thus in the synthesis of tri-from mono-substituted esters the order of introduction of
    在改良的情况下,已经通过使用Schlessinger等人最初提出的方法研究了在六甲基磷酰胺存在下,烷基碘化物以二异丙基氨基锂为碱,通过烷基碘化物使羧酸酯烷基化的空间极限。如前所述,已经研究了六甲基磷酰胺在促进酯烯化中的作用,与其对烷基化步骤的影响相反。由α-单取代酯形成αα-二取代酯的收率很高,而且似乎仅受烷基化剂性质的影响(Mel,Etl或Pr il)。相反,对于αα-二取代酯,形成αα-三取代的αα似乎对要烷基化的酯的空间性质敏感。因此,在三-单取代酯的合成中,烷基的引入顺序至关重要。某些酯不能反应的解释是由于不能进行烯醇化。
