  摘要：

  摘要 从Olinia emarginata 的叶子和枝条中分离到了含氰葡萄糖苷prunasin (2-β-d-glucopyranosyloxy-2-phenylacetonitrile)。它还在 O. ventosa、O. radiata 和 O. rochetiana 的叶和茎中被鉴定和量化。从O. ventosa的叶子中分离得到相应的扁桃酸酰胺糖苷（2-β-d-吡喃葡萄糖基氧基-2-苯乙酸酰胺），主要通过核磁共振谱数据及其降解产物进行鉴定；它也发生在 O. emarginata 的叶子中。这是氰基葡糖苷及其相应酰胺共存的第一个例子，表明 prunasin 的腈基可能水合为羧酰胺而不影响糖苷键；这种反应由腈水合酶催化。

• Substrate Evaluation of<i>Rhodococcus erythropolis</i>SET1, a Nitrile Hydrolysing Bacterium, Demonstrating Dual Activity Strongly Dependent on Nitrile Sub-Structure
  作者：Tracey M. Coady、Lee V. Coffey、Catherine O'Reilly、Claire M. Lennon

  DOI：10.1002/ejoc.201403201

  日期：2015.2

  Rhodococcus erythropolis SET1, a novel nitrile hydrolysing bacterial isolate, has been undertaken with 34 nitriles, 33 chiral and 1 prochiral. These substrates consist primarily of β-hydroxy nitriles with varying alkyl and aryl groups at the β position and containing in several compounds different substituents α to the nitrile. In the case of β-hydroxy nitriles without substitution at the α position

  红球菌 SET1 是一种新型腈水解细菌分离株，已使用 34 种腈、33 种手性和 1 种前手性进行了评估。这些底物主要由 β-羟基腈组成，在 β 位具有不同的烷基和芳基，并且在几种化合物中含有与腈不同的 α 取代基。在 α 位没有取代的 β-羟基腈的情况下，由于分离物的腈水解酶活性，酸是获得的主要产物，以及生物转化后回收的腈。出乎意料的是，当 β-羟基腈在该位置具有乙烯基时，发现酰胺是主要的水解产物。为了进一步探索这种行为，评估了在 α 位置包含吸电子基团的其他相关底物，在 SET1 存在下的生物转化过程中也观察到了酰胺。因此，这种新的分离物也证明了对似乎是底物依赖性的腈类的 NHase 活性。
• Probing the enantioselectivity of a diverse group of purified cobalt-centred nitrile hydratases

  日期：——

  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。

• Hydration of Cyanohydrins by Highly Active Cationic Pt Catalysts: Mechanism and Scope

  Cyanohydrins (α-hydroxy nitriles) are a special type of nitriles that readily decompose into hydrogen cyanide (HCN) and the corresponding carbonyl compounds. Hydration of cyanohydrins that are readily available through cyanation of aldehydes and ketones provides the most straightforward route to valuable α-hydroxyamides. However, due to low stability of cyanohydrins and deactivation of the catalysts

  氰醇（α-羟基腈）是一种特殊类型的腈，很容易分解成氰化氢 (HCN) 和相应的羰基化合物。可通过醛和酮的氰化轻松获得的氰醇的水合提供了获得有价值的 α-羟基酰胺的最直接途径。然而，由于氰醇的低稳定性和释放的 HCN 使催化剂失活，氰醇的催化直接水合仍然在很大程度上未解决。一般来说，含有较大取代基的氰醇，如α,α-二芳基氰醇，降解速度更快，因此更难水合。在这里，我们报告了对各种氰醇的水合表现出高反应性的阳离子铂催化剂的开发。2 OH)X(OTf) 揭示了一个催化循环，包括形成五元金属环中间体，然后通过 H 2 O攻击二级氧化膦 (PR 2 OH) 配体的磷进行水解。我们发现 Pt 催化剂甲轴承富电子，适当小的咬角双膦配体提供了一种用于氰醇的水合反应性超级。由A催化的水合反应在环境温度下进行，并与多种氰醇一起发生，包括最难的 α,α-二芳基氰醇，具有良好的转化率。
