  硼化芳烃的加氢

  摘要：

  据报道，环状（烷基）（氨基）卡宾铑（Rh–CAAC）催化了丰富的芳基硼酸及其衍生物的顺式选择性氢化。该反应可耐受各种硼保护基，并可以直接进入具有各种官能团的各种饱和，硼化的碳环和杂环。该转变在战略上很重要，因为通用的饱和硼酸酯产品很难用其他方法制备。硼基的后官能化证明了饱和环状结构单元的效用。

  二级和三级硼酸酯与芳香族化合物的对映体特异性偶联的发展

  摘要：

  仲硼酸酯与 sp2 亲电试剂的立体有择交叉偶联（Suzuki-Miyaura 反应）是合成中长期存在的问题，但在使用钯催化的特定情况下已经取得了进展。然而，目前无法实现与叔硼酸酯的相关偶联。为了解决这一普遍问题，我们专注于利用芳基锂和硼酸酯之间形成的硼酸盐络合物的反应性的替代方法。我们推断，随后添加氧化剂或亲电子试剂会分别从芳环中去除电子或以 Friedel-Crafts 型方式反应，产生阳离子物质，这将引发硼取代基的 1,2-迁移，创建新的 C-C 键。消除（在前一种情况下，在进一步氧化之前）将导致重新芳构化，从而立体特异性地产生偶联产物。最初的工作是用 2-furyllithium 检查的。尽管测试的氧化剂不成功，但亲电试剂，特别是 NBS，使得偶联反应能够以良好的收率与范围广泛的仲和叔硼酸酯发生偶联反应，具有不同的空间需求和官能团（酯、叠氮化物、腈、醇和醚） ）。该反应也适用于其他富电子杂芳烃和

• Suzuki–Miyaura cross-coupling reaction of aryl and heteroaryl pinacol boronates for the synthesis of 2-substituted pyrimidines
  作者：Shigehiro Asano、Seiji Kamioka、Yoshiaki Isobe

  DOI：10.1016/j.tet.2011.10.057

  日期：2012.1

  Suzuki–Miyaura cross-coupling reaction with 2-heteroarylboronic acids is generally challenging due to these acids easy decomposition. To overcome this problem, we developed a coupling method that uses 2-heteroaryl pinacol boronates in the presence of 1.0 mol % Pd(OAc)2 and 2.0 mol % S-Phos with 4 equiv amount of LiOH in dioxane and H2O at 80 °C for 30 min. This developed method allowed for the synthesis

  由于这些酸易于分解，因此与2-杂芳基硼酸的铃木-宫浦交叉偶联反应通常具有挑战性。为克服此问题，我们开发了一种偶合方法，该方法在1.0 mol％Pd（OAc）2和2.0 mol％S-Phos的存在下，在80％的二恶烷和H 2 O中于80摩尔下使用2-杂芳基频哪醇硼酸酯°C 30分钟。这种发达的方法允许从2-氯嘧啶基衍生物高产率地合成各种各样的2-杂芳基嘧啶，并且还可以用于由杂芳基氯化物制备各种联芳基衍生物。

  complexed in a 1:1 ratio with Pd(OAc)2, enables Pd‐catalyzed cross‐couplings to be run using ≤1000 ppm of this pre‐catalyst. Applications to Suzuki–Miyaura reactions involving highly funtionalized reaction partners are demonstrated, all run using environmentally benign nanoreactors in water at ambient temperatures. Comparisons with existing state‐of‐the‐art ligands and catalysts are discussed herein.
