  摘要：

  AbstractThe cross‐coupling reaction of chloro‐ and bromomethyl oxime ethers with a wide range of aryl‐, heteroaryl‐ and vinylboronic acids in the presence of catalytic palladium complexes with different phosphines has been carried out with good yields (60–98%, 40 examples). Regioselective cross‐coupling reactions differentiating between an alkyl or aryl position are achieved from dihalo oxime ethers containing Csp2‐ and Csp3‐halogen bonds using mono‐ or dicoordinated palladium catalysts such as Pd(dba)2/P(o‐tolyl)3 or Pd(PPh3)4. The selective orthogonal functionalization of dihalo oxime ethers is also described. Site‐selective transformations allow the introduction of the biaryl motif into dihalo oxime ethers preserving the highly activated alkyl halide moiety vicinal to the oxime group for further transformations. In this context, Z‐ and E‐oxime ethers could be considered as synthetic equivalents of ketones in palladium‐catalyzed Suzuki reactions.magnified image

  Palladium-catalyzed C–H activation/C–C cross-coupling reactions have emerged as attractive tools for organic synthesis. Typically, these reactions require stoichiometric chemical oxidants and exogenous ligands to regenerate the palladium catalyst and promote reductive elimination respectively. However, there are significant disadvantages associated with the use of traditional stoichiometric oxidants

  钯催化的C–H活化/ C–C交叉偶联反应已成为有机合成的诱人工具。通常，这些反应需要化学计量的化学氧化剂和外源性配体以分别再生钯催化剂并促进还原消除。然而，使用传统的化学计量的氧化剂存在显着的缺点，包括原子经济性差，副产物形成和高成本。为了克服这些问题，我们开发了一种电化学策略，利用PdII的阳极氧化来诱导选择性的C–C还原消除，从而分别使用硼试剂和α-酮酸实现甲基化和酰化。

This CI coupling reaction occurred at room temperature with high regio‐selectivity and functional‐group compatibility. Subsequent diversified nucleophilic functionalization of

  A rhodium(III)-catalyzed redox-neutral ring-opening of 7-azabenzonorbornadienes with aromatic ketoximes giving 2-arylated hydronaphthylamines in a highly diastereoselective manner is described. Later, the 2-arylated hydronaphthylamines were converted into highly sensitive 13,14-dehydro benzophenanthridine derivatives by HCl hydrolysis. Further, 13,14-dehydro benzophenanthridines were aromatized into

  AbstractThe three‐component reaction of α‐halomethyl oxime ethers, boronic acids and carbon monoxide at atmospheric pressure catalyzed by tetrakis(triphenylphosphine)palladium(0) gives efficiently unsymmetrical β‐alkoxyimino carbonyl compounds with total control of the regioselectivity, in high yield and atomic economy. Simple commercially available starting materials are used in this synthetic procedure. The three components assembly takes place preferentially versus the competing direct coupling or other possible side reactions. The mechanism of the transformation was investigated by NMR and intermediate palladium(II) complexes were detected.magnified image
