  Transition-Metal-Free Self-Hydrogen-Transferring Allylic Isomerization

  摘要：

  Phenanthroline and tert-butoxide have been established as powerful radical initiators in reactions such as the S(RN)1-type coupling reactions due to the cooperation of large heteroarenes and a special feature of tert-butoxide. The first phenanthroline-tert-butoxide-catalyzed transition-metal-free allylic isomerization is described. The resulting ketones are key intermediates for indenes. The control experiments rule out the base-promoted allylic anion pathway. The radical pathway is supported by experimental evidence that includes kinetic study, kinetic isotope effect, isotope-labeling experiments, trapping experiments, and EPR experiments.

  吲哚和Ch的溶剂依赖性铜催化形成的合成和机理研究

  摘要：

  已经发现负载在活性炭上的铜纳米颗粒可以催化吡啶-2-甲醛醛衍生物，仲胺和末端炔烃在二氯甲烷中吲哚嗪的多组分合成。然而，在没有溶剂的情况下，形成杂环查耳酮。我们提供了令人信服的证据，表明这两个过程都是通过醛-胺-炔烃偶联中间体进行的。与其他从醛和炔烃形成查耳酮的众所周知的机理相反，提出了一种新的反应途径，其中涉及炔丙基胺作为不进行重排的中间体。吲哚嗪或查耳酮的形成是由感应效应和溶剂效应驱动的，广泛报道了两者。在两个反应中

  The first Fe-facilitated decarboxylative cross-coupling reaction between α-oxocarboxylic acids and acrylic acids in aqueous solution has been developed. This transformation is characterized by its wide substrate scope and good functional group compatibility utilizing inexpensive and easily accessible reagents, thus providing an efficient and expeditious approach to an important class of α,β-unsaturated

  An effective strategy for synthesis of Cu nanoparticles is designed, these nanoparticles have high catalytic activity in conjugate addition of B2(pin)2 and α,β-unsaturated ketones. The reaction of protodeboration can proceed with adding NaOtBu. In this way, a new method to reduce the conjugated alkenes of α,β-unsaturated ketones is developed with organoboranes as intermediates.

  Copper complexes of phosphoramidites efficiently catalyzed asymmetric addition of arylboron reagents to acyclic enones. Importantly, rare 1,4-insertion of arylcopper(I) was identified which led directly to O-bound copper enolates. The new mechanism is fundamentally different from classical oxidative addition/reductive elimination of organocopper(I) on enones.
