  通过 Pd 催化的 Suzuki-Miyaura 反应对映选择性合成轴向手性联芳基化合物：底物范围和量子力学研究

  摘要：

  我们报告了轴向手性联芳酰胺的有效合成，产率范围为 80-92%，对映选择性范围为 88-94% ee，采用不对称 Suzuki-Miyaura 工艺，Pd(OAc)(2) 和 KenPhos 作为配体。这些研究表明，富电子和缺电子的邻卤苯甲酰胺可以与 2-甲基-1-萘基硼酸和 2-乙氧基-1-萘基硼酸有效偶联。反应的产率和选择性与苯甲酰胺偶联伙伴上卤素取代基的性质无关。我们的研究表明，轴向手性杂环和联苯化合物也可以用这种方法合成。我们还报告了用于确定在甲苯基硼酸与萘基膦酸酯溴化物相关偶联的选择性决定还原消除步骤期间立体选择性起源的计算研究，该步骤在之前的出版物中报道过 (J. Am. Chem. Soc. 2000, 122 , 12051-12052)。这些研究表明，立体选择性源于弱 -(C)H..O 相互作用以及 CC 偶联过渡态中甲苯基和萘基膦酸酯加合物之间的空间相互作用。

  functions with nearly identical efficiency in terms of yield and enantioselectivity. Catalyst discovery and development, the optimization of reaction conditions, the exploration of reaction scope, and applications in target‐directed synthesis are reported. Experimental observations suggest that these alkylation reactions occur through an unusual inner‐sphere mechanism involving binding of the prochiral

• Investigation of the Mechanism of C(sp³)−H Bond Cleavage in Pd(0)-Catalyzed Intramolecular Alkane Arylation Adjacent to Amides and Sulfonamides
  作者：Sophie Rousseaux、Serge I. Gorelsky、Benjamin K. W. Chung、Keith Fagnou

  DOI：10.1021/ja103081n

  日期：2010.8.11

  reactivity of C(sp(3))-H bonds adjacent to a nitrogen atom can be tuned to allow intramolecular alkane arylation under Pd(0) catalysis. Diminishing the Lewis basicity of the nitrogen lone pair is crucial for this catalytic activity. A range of N-methylamides and sulfonamides react exclusively at primary C(sp(3))-H bonds to afford the products of alkane arylation in good yields. The isolation of a Pd(II) reaction

  可以调整与氮原子相邻的 C(sp(3))-H 键的反应性，以允许在 Pd(0) 催化下进行分子内烷烃芳基化。降低氮孤对的路易斯碱度对于这种催化活性至关重要。一系列 N-甲基酰胺和磺酰胺仅在初级 C(sp(3))-H 键上反应，以高产率提供烷烃芳基化产物。Pd(II) 反应中间体的分离使得能够评估反应机理，重点是碱在 C(sp(3))-H 键断裂步骤中的作用。这些化学计量研究的结果，连同动力学同位素效应实验，为协调的金属化-去质子化 (CMD) 过渡态提供了罕见的实验支持，此前已在烷烃 C(sp(3))-H 芳基化中提出了这种过渡态。而且，DFT 计算揭示了新戊酸盐添加剂作为磷化氢从 Pd(II) 中间体解离的促进剂的额外作用，使 CMD 过渡态成为可能。最后，进行了动力学研究，揭示了反应速率表达及其与新戊酸盐浓度的关系。

  enylboronic acid were identified as efficient catalysts for the direct and chemoselective activation of oxime N-OH bonds in the Beckmann rearrangement. This classical organic reaction provides a unique approach to prepare functionalized amide products that may be difficult to access using traditional amide coupling between carboxylic acids and amines. Using only 5 mol % of boronic acid catalyst and
