  Enantioselective conversion of α-arylnitriles by Klebsiella oxytoca

  摘要：

  A new bacterial isolate Klebsiella oxytoca 38.1.2 with stereoselective nitrile hydratase activity against rac-2-phenylglycine nitrile, rac-2-phenylpropionitrile and rac-mandelonitrile was investigated. The cultivation conditions for growth and nitrile hydratase formation were studied. An intracellular (S)-enantioselective nitrile hydratase and a putative (S)-selective amidase were found to be induced in the presence of rac-2-phenylpropionitrile. The temperature dependence on the enantioselectivity of the nitrile hydratase active cells was studied in more detail for the biotransformation of rac-2-phenylpropionitrile and rac-mandelonitrile. By increasing the temperature from 15 degrees C to 37 degrees C, the apparent enantiomeric ratio of the conversion of rac-2-phenylpropionitrile to (S)-2-phenylpropionamide increased from 16 to 35 at nearly 50% conversion rate. rac-Mandelonitrile was converted to (S)-mandelamide with an enantiomeric excess of up to 95% in a 80% yield without further conversion to mandelic acid.

  未受保护的肽中羧酰胺的位点选择性芳基化

  摘要：

  酰胺化肽因其独特的生物学特性和作为潜在肽药物和生物标志物的广泛应用而成为一类重要的生物活性化合物。尽管天然肽中含有丰富的游离酰胺基序（Asn、Gln 和 C 端酰胺），但天然肽中酰胺单元的后期修饰仍然非常罕见，因为酰胺本身亲核性较弱，并且存在多个竞争性亲核残基的干扰，通常会导致不希望的副反应。在此，已在空气气氛下开发了未受保护的多肽中酰胺的化学选择性芳基化，以提供N-带有各种功能基序的芳基酰胺肽。它的成功依赖于金催化和银盐的结合，以区分一系列反应性亲核氨基酸残基（例如，-NH 2、-OH和-COOH）中相对惰性的酰胺，有利于C-N键偶联酰胺优于其他亲核基团。实验和 DFT 研究揭示了银阳离子的关键作用，它充当更具反应性的反应位点的瞬时配位掩模，克服了酰胺固有的低反应性。该策略优异的生物相容性已应用于多种肽药物和复合肽的功能化。该应用可以进一步扩展到肽标记和肽装订。

  In this study a diverse range of purified cobalt containing nitrile hydratases (NHases, EC 4.2.1.84) from Rhodopseudomonas palustris HaA2 (HaA2), Rhodopseudomonas palustris CGA009 (009), Sinorhizobium meliloti 1021 (1021), and Nitriliruptor alkaliphilus (iso2), were screened for the first time for their enantioselectivity towards a broad range of chiral nitriles. Enantiomeric ratios of >100 were found for the NHases from HaA2 and CGA009 on 2-phenylpropionitrile. In contrast, the Fe-containing NHase from the well-characterized Rhodococcus erythropolis AJ270 (AJ270) was practically aselective with a range of different α-phenylacetonitriles. In general, at least one bulky group in close proximity to the α-position of the chiral nitriles seemed to be necessary for enantioselectivity with all NHases tested. Nitrile groups attached to a quaternary carbon atom were only reluctantly accepted and showed no selectivity. Enantiomeric ratios of 80 and >100 for AJ270 and iso2, respectively, were found for the pharmaceutical intermediate naproxennitrile, and 3-(1-cyanoethyl)benzoic acid was hydrated to the corresponding amide by iso2 with an enantiomeric ratio of >100.

  在本研究中，首次对来自红假单胞菌HaA2（HaA2）、红假单胞菌CGA009（009）、豌豆根瘤菌1021（1021）和嗜碱氮裂解菌（iso2）的多种纯化钴含氮裂解酶（NHases，EC 4.2.1.84）对一系列手性腈的立体选择性进行了筛选。对于2-苯基丙腈，来自HaA2和CGA009的NHases的立体异构比大于100。相比之下，来自已知红球菌AJ270（AJ270）的含铁NHase对一系列不同α-苯基乙腈实际上没有选择性。总的来说，对于所有测试的NHases来说，似乎至少需要一个在α-位附近的大体积基团才能实现立体选择性。连接在四级碳原子上的腈基团仅勉强被接受，并且没有显示出选择性。对于药物中间体萘普生腈，AJ270和iso2的立体异构比分别为80和大于100；iso2还将3-（1-氰乙基）苯甲酸水合为相应的酰胺，立体异构比大于100。

  the pharmacological importance of ortho-arylbenzylamines, however, effective ortho-C-C bond formation of free primary and secondary benzylamines using PdII remains an outstanding challenge. Presented herein is a new strategy for constructing ortho-arylated primary and secondary benzylamines mediated by carbon dioxide (CO2). The use of CO2 with Pd is critical to allowing this transformation to proceed

  通过过渡金属催化的 CH 活化形成 CC 键已成为快速制造新键的重要策略。然而，尽管邻芳基苄胺具有药理学重要性，但使用 PdII 形成游离伯胺和仲苄胺的有效邻 CC 键仍然是一个突出的挑战。本文提出了一种用于构建由二氧化碳 (CO2) 介导的邻位芳基化伯和仲苄胺的新策略。CO2 与 Pd 的使用对于允许这种转化在相对温和的条件下进行至关重要，机械研究表明它 (CO2) 直接参与速率决定步骤。此外，较温和的温度提供了无需脱保护即可直接使用或加工的游离胺产品。

  We report here a novel method for the modular synthesis of highly substituted piperazines and related bis-nitrogen heterocycles via a palladium-catalyzed cyclization reaction. The process couples two of the carbons of a propargyl unit with various diamine components to provide nitrogen heterocycles in generally good to excellent yields and high regio- and stereochemical control.
