  受锂离子电池化学启发的可扩展且安全的合成有机电解还原

  摘要：

  大规模无钠桦木还原尽管条件艰巨，化学家仍经常使用所谓的桦木还原：将发火钠溶解在纯液氨中以实现芳烃的部分还原。彼得斯等人。研究并优化了小规模电化学替代方案，以设计出一种更安全的方案，可以在更大范围内使用各种功能复杂的底物。科学，本期第 14 页。838 优化的电化学条件比溶解在氨中的钠更安全地还原各种芳香族底物。还原电合成在复杂有机基质的大规模应用中面临着长期的挑战。在这里，我们展示了数十年对锂离子电池材料、电解质和添加剂的研究如何为实现 Birch 还原的实际可扩展的还原电合成条件提供灵感。具体来说，我们证明，使用牺牲阳极材料（镁或铝），结合廉价、无毒、水溶性质子源（二甲基脲）以及受电池技术[三（吡咯烷）磷酰胺]启发的过充电保护剂可以允许用于医药相关结构单元的多克规模合成。我们展示了这些条件如何相对于经典的电化学和化学溶解金属还原具有非常高水平的官能团耐受性。最后，我们证明相同的电化学条件可以应用于其他溶解金属型还原转化，包括

  A nickel-catalyzed decarbonylative silylation, borylation, and amination of amides has been developed. This new methodology allows the direct interconversion of amides to arylsilanes, arylboronates, and arylamines and enables a facile route for carbon–heteroatom bond formations in a straightforward and mild fashion.

• Cine Substitution of Arenes Using the Aryl Carbamate as a Removable Directing Group
  作者：Tehetena Mesganaw、Noah F. Fine Nathel、Neil K. Garg

  DOI：10.1021/ol301275u

  日期：2012.6.1

  An efficient and controlled means to achieve a rare cine substitution of arenes is reported. The methodology relies on the strategic use of aryl O-carbamates as readily removable directing groups for arene functionallzation. The removal of aryl carbamates is achieved by employing an airstable Ni(II) precatalyst, along with an inexpensive reducing agent, to give synthetically useful yields across a range of substrates. The net cine substitution process offers a new strategy for analogue synthesis, which complements the well-established logic for achieving arene functionalization by ipso substitution.

  日期：2014.2.12

  A Ni/Cu-catalyzed silylation of unactivated C-O electrophiles derived from phenols or benzyl alcohols is described. This transformation is characterized by its wide scope and mild conditions, providing a direct access to synthetically versatile silylated compounds. The protocol allows for the coupling of C(sp(2))-O and even C(sp(3))-O bonds with similar efficiency.
• Direct and Selective Arylation of Tertiary Silanes with Rhodium Catalyst
  作者：Yoshinori Yamanoi、Hiroshi Nishihara

  DOI：10.1021/jo8008148

  日期：2008.9.1

  We have developed a convenient and efficient approach to the arylation of tertiary silanes under mild conditions. A variety of arylsilanes were synthesized in a one-step process with good to excellent yields in the presence of a rhodium catalyst with a base. The reaction was highly solvent dependent, and amides were the most effective of the various solvents used. This common catalyst system is highly tolerant of the various sensitive functional groups on the substrates, which might be difficult to extract by other methods. The rhodium-promoted silylation of aryl halides with electron-donating groups occurred more efficiently than the silylation of aryl halides substituted with electron-withdrawing groups. Heteroaromatic halides were also found to be readily silylated with tertiary silanes. The successful application of this reaction to the synthesis of a TAC-101 analogue, which is a trialkylsilyl-containing synthetic retinoid benzoic acid derivative with selective binding affinity for retinoic acid receptor-alpha, is also described.
