  Straightforward protocol for the efficient synthesis of varied N1-acylated (aza)indole 2-/3-alkanoic acids and esters: optimization and scale-up

  摘要：

  A library of approximately 40 N-1-acylated (aza)indole alkanoic esters and acids was prepared employing a microwave-assisted approach. The optimized synthetic route allows for parallel synthesis, variation of the indole substitution pattern, and high overall yield. Additionally, the procedure has been scaled up to yield multi-gram amounts of preferred indole compounds, e.g.: 2'-des-methyl indomethacin 2. The reported compounds were designed as biomedical tools for primary and secondary in vitro and in vivo studies at relevant molecular targets. (C) 2012 Elsevier Ltd. All rights reserved.

  was developed for the purpose of generating radicals via direct photoexcitation. These borates were prepared using 2,2′-(pyridine-2,6-diyl)diphenol as a tridentate ligand together with organoboronic acids or potassium trifluoroborates. The ready availability of organoboron compounds is a significant advantage of this direct photoexcitation protocol. The excited states of these borates can also serve

  The generation of tertiary, secondary, and primary alkyl radicals has been achieved by the direct visible-light excita-tion of a boracene-based alkylborate. This system is based on the photophysical properties of the organoboron mole-cule. The protocol is applicable to decyanoalkylation, Giese addition, and nickel-catalyzed carbon-carbon bond for-mations such as alkyl-aryl cross-coupling or vicinal

  reactions rely on the discovery of unusually persistent organonickel complexes that serve as stoichiometric platforms for C(sp2)–C(sp3) coupling. Aryl, heteroaryl or vinyl complexes of Ni can be inexpensively prepared on a multigram scale by mild electroreduction from the corresponding C(sp2) electrophile. Organonickel complexes can be isolated and stored or telescoped directly to reliably diversify

  构建 C sp 2 –C sp 3键的重要性推动了电化学、光化学和热活化方法的发展，以还原偶联丰富的芳基和烷基亲电子试剂。然而，这些方法仅限于非常特定的底物类别的耦合，并且需要专门的催化剂组和反应装置。在这里，我们展示了将这些无数的策略整合到一组条件中，以实现可靠的烷基芳基偶联，包括那些以前未知的偶联。这些反应依赖于异常持久的有机镍配合物的发现，该配合物可作为 C( sp 2 )–C( sp 3 ) 偶联的化学计量平台。 Ni的芳基、杂芳基或乙烯基配合物可以通过相应的C( sp 2 )亲电子试剂的温和电还原以数克规模廉价地制备。有机镍络合物可以被分离和储存或直接伸缩，以可靠地多样化药物样分子。最后，通过整合可溶性电池化学物质作为氧化还原引发剂，将该过程小型化至微摩尔尺度，从而实现底物多样性的高通量探索。
