  Stereoselective synthesis of both enantiomers of N-Boc-α-aryl-γ-aminobutyric acids

  摘要：

  Esterification of racemic alpha-aryl-beta-cyanopropionic acid chlorides with either (R)- or (S)-N-phenylpantolactam as the chiral auxiliary in the presence of Et3N resulted in the predominant formation of (alphaR,3'R)- or (alphaS,3'S)-configured pantolactam cyano ester, respectively, in nearly quantitative yields with diastereomeric ratios of up to 93:7. Column chromatography of the diastereoenriched cyano esters, followed by hydrolysis of the resulting diastereopure cyano esters under essentially nonracemizing conditions gave enantiopure alpha-aryl-beta-cyanopropionic acids, which were readily converted in high yields into enantiopure (OER)- and (alphaS)-configured N-tert-butoxycarbonyl-alpha-aryl-gamma-aminobutyric acid (GABA) derivatives of potential biological interest.

  carboxylic acid building blocks, a β‐substituted phenylpropanoic acid, a cyclic γ‐keto carboxylic acid and a mononitrile monocarboxylic acid, were achieved from the corresponding nitrile substrates, using three new nitrilases (two from Sphingomonas wittichii and one from Syntrophobacter fumaroxidans). Improvements of nitrilase activities through the optimization of reaction parameters and the preparative

  针对25种结构多样的底物进行高通量的候选腈水解酶筛选，使我们能够创建125种经过实验验证的腈水解酶的广泛集合。通过基因组方法从700种多样的原核物种和一个作为亚硝化酶家族多样性代表的元基因组中选择了这些酶。通过提供大量经过测试的腈水解酶及其指定的底物，该酶标物的酶促筛选扩展了用于化学合成的生物催化工具箱。三个例子说明了我们酶的合成潜力。使用三个新的腈水解酶（其中两个来自腈水解酶）从相应的腈底物上合成了羧酸结构单元，β-取代的苯基丙酸，环状的γ-酮基羧酸和单腈一元羧酸Sphingomonas wittichii和一种来自Sumtrophobacter fumaroxidans的细菌。通过这三个实例，通过优化反应参数和制备型生物催化合成方法改善了腈水解酶的活性。
