  使用双亲氨基硼烷对杂芳烃进行无金属硼酸化：关于空间在受阻路易斯对 CH 键活化中的重要性

  摘要：

  两种新型受阻路易斯对 (FLP) 氨基硼烷，(1-Pip-2-BH2-C6H4)2 (2; Pip = 哌啶基) 和 (1-NEt2-2-BH2-C6H4)2 (3; NEt2 = 二乙氨基)，合成，并阐明了它们在溶液和固态中的结构特征。研究了这些物质对杂芳烃硼化的反应性，并与之前报道的 (1-TMP-2-BH2-C6H4)2 (1; TMP = 四甲基哌啶基) 和 (1-NMe2-2-BH2-C6H4)2 ( 4；NMe2 = 二甲氨基）。结果表明，2 和 3 是比体积更大的类似物 1 更活跃的杂芳烃硼化催化剂。用 1 和 2 进行动力学研究和密度泛函理论计算，以确定这种 FLP 催化转化的氨基的影响。发现 CH 活化步骤对于较小的胺更容易，但代价是二聚体更难解离。所有催化剂 (1F-4F) 的实验室稳定氟硼酸盐已被合成并测试了硼化反应。新的预催化剂 2F 和 3F 在多克级合成中显示出更高的反应速率和产率。

Ligand 1 has demonstrated excellent performance for coupling reactions of extremely hindered arylboronic acids.

We demonstrate that it can be combined with metal–halogen exchange reactions or a variety of directed ortho metalation protocols in a “one-pot” sequence for the synthesis of aromatic amines with unique substitution patterns.

  通过使用常见的廉价亲电氮源（H 2 N-OSO 3H，HSA）。通过这种方法发现富含电子的底物具有最高的反应性。但是，在室温条件下，即使是中等电子贫乏的基材也能很好地耐受。与不受阻碍的基材相比，受阻的基材似乎同样有效。高度缺乏电子的底物在室温下以非常低的产率提供产物，但是在回流温度下获得中等至良好的产率。我们的方法也适用于几种常见的硼酸衍生物（例如频哪醇酯）的亲电胺化反应。我们证明了它可以与金属-卤素交换反应或各种定向的邻位金属化方案以“一锅”顺序结合使用，以合成具有独特取代模式的芳香胺。DFT研究，结合实验结果，表明该反应是通过碱介导的HSA活化发生的，然后发生1,2芳基B–N迁移。这种活化方式对于反应的成功似乎至关重要，并且首次允许在环境温度下对硼酸进行一般的亲电子胺化。

This synthetic method uses inexpensive and conveniently synthesizable bench-stable precatalysts of the form 1-NHR2-2-BF3-C6H4, commercially and synthetically accessible heteroarenes as substrates, and pinacolborane as the borylation reagent.

  diphosphine effectively promotes the intramolecular addition of the C(sp3)−H bond across a carbon–carbon double bond in a highly enantioselective fashion. The reaction gives indolines bearing a quaternary stereogenic carbon center at the 3‐position. The reaction mechanism involves rate‐determining oxidative addition of the N‐methyl C−H bond, followed by intramolecular carboiridation and subsequent reductive
