• Microbial hydrolysis as a potent method for the preparation of optically active nitriles, amides and carboxylic acids
  作者：Hideaki Kakeya、Naoko Sakai、Takeshi Sugai、Hiromichi Ohta

  Many kinds of aromatic nitriles have been hydrolyzed to afford the corresponding amides and carboxylic acids, by the aid of enzyme system of Rhodococcus butanica. This enzymatic hydrolysis can be successfully applied to the kinetic resolution of α-arylpropionitriles, resulting in the formation of (R)-amides and (S)-carboxylic acids.

  日期：——

  We have identified a novel one-pot method for the synthesis of β-amino alcohols, which is based on C–H bond hydroxylation at the benzylic α-carbon atom with a subsequent nitrile or amide functional group reduction. This cascade process uses molecular oxygen as an oxidant and sodium bis(2-methoxyethoxy)aluminum hydride as a reductant. The substrate scope was examined on 30 entries and, although the

  我们已经确定了一种用于合成 β-氨基醇的新型一锅法，该方法基于苄基 α-碳原子上的 C-H 键羟基化，随后腈或酰胺官能团还原。这种级联过程使用分子氧作为氧化剂和双（2-甲氧基乙氧基）氢化铝钠作为还原剂。对 30 个条目检查了底物范围，尽管相应产品仅以中等产率提供，但上述简单方案可作为其他难以制备的空间拥挤 1,2-氨基醇的直接且有力的入口路线。给出了观察结果的合理机械原理，并将反应应用于潜在生物活性靶标的合成。
• Nickel-Catalyzed Markovnikov Transfer Hydrocyanation in the Absence of Lewis Acid
  作者：Nils L. Frye、Anup Bhunia、Armido Studer

  DOI：10.1021/acs.orglett.0c01454

  日期：2020.6.5

  Hydrocyanation in the absence of toxic HCN gas is highly desirable. Addressing that challenge, transition-metal-catalyzed transfer hydrocyanation using safe HCN precursors has been developed, but these reagents generally require a Lewis acid for activation, and the control of regioselectivity often remains problematic. In this Letter, a Ni-catalyzed highly Markovnikov-selective transfer hydrocyanation

  在没有有毒的HCN气体的情况下进行氢氰化是非常需要的。为了应对这一挑战，已经开发出使用安全的HCN前体的过渡金属催化的转移氢氰化反应，但是这些试剂通常需要路易斯酸进行活化，并且对区域选择性的控制通常仍然存在问题。在这封信中，报道了在没有任何路易斯酸的情况下进行的镍催化的高度马尔可夫尼科夫选择性转移氢氰化反应。易制得的原芳族1-异丙基环己-2,5-二烯-1-腈作为HCN源，该反应显示出较宽的底物范围和较高的官能团耐受性。将末端苯乙烯衍生物，二烯和内部炔烃以良好的选择性转化为优异的选择性。机理研究为区域选择性的起源提供了见识。

  methods to prepare aryl nitriles and vinyl nitriles from aryl halides and alkynes, respectively. Using inexpensive and non-toxic 4-cyanopyridine N-oxide as the cyano shuttle, the methods provide an efficient approach to prepare aryl cyanides and vinyl nitriles under mild and operationally simple reaction conditions with a broad range of functional group tolerance. In hydrocyanation of alkynes, the method

  我们报告镍催化氰化和氢氰化方法分别从芳基卤化物和炔烃制备芳基腈和乙烯基腈。使用廉价且无毒的4-氰基吡啶N-氧化物作为氰基梭，该方法提供了一种在温和且操作简单的反应条件下制备具有宽泛官能团耐受性的芳基氰化物和乙烯基腈的有效方法。在炔烃的氢氰化中，该方法表现出良好的区域选择性，可控方式主要产生E或Z烯基腈，而分别以内部二芳基炔烃和末端炔烃为底物时，则仅产生马尔可夫尼科夫乙烯基腈。

  Herein, we present m-C–H olefination on derivatives of phenylacetic acids by tethering with a simple nitrile-based template through palladium catalysis. Notably, the versatility of the method is evaluated with a wide range of phenylacetic acid derivatives for obtaining the meta-olefination products in fair to excellent yields with outstanding selectivities under mild conditions. Significantly, the

  在此，我们通过钯催化与简单的腈基模板连接，在苯乙酸衍生物上进行m -C-H 烯化。值得注意的是，该方法的多功能性是用范围广泛的苯乙酸衍生物来评估的，以便在温和的条件下以中等至极好的收率和出色的选择性获得间烯烃化产物。重要的是，本策略成功地用于合成药物/天然产物类似物（萘普生、布洛芬、扑热息痛和胆固醇）。
