  铜催化 2-(1-炔基)苯扎二亚胺与水串联反应构建异喹啉-1(2H)-酮

  摘要：

  开发了 Cu(OAc)2 催化的 2-(1-炔基) 苯并二亚胺与水的串联反应，用于合成异喹啉-1(2H)-酮。此外，只需在反应体系中加入 N-卤代琥珀酰亚胺（NXS：X = Cl、Br、I），即可以良好的收率获得 4-卤素取代的异喹啉-1(2H)-酮。机理研究表明，该反应可能是由 2-(1-炔基) 苯扎二亚胺的高度区域选择性分子内环化引发的，生成相应的异喹啉鎓中间体。

  Synthesis of Heterocycles with MF/Al 2 O 3 Base-Systems: 2-Arylbenzofuranes and 2,3-Diarylisoquinolin-1(2H)-ones2-Benzyloxybenzaldehydes, -acetophenones and -benzophenones substituted in the benzyl part with electron-withdrawing groups, cyclize easily to 2-arylbenzofuranes by using a standardized KF- or CsF-Al2O3 base system. An efficient one-pot synthesis for 2,3-diarylisoquinolin-1(2H)-ones is possible by reacting a variety of arene carbaldehyde anils with phthalides under the same reaction conditions.

  An efficient method for the synthesis of substituted 1(2H)‐isoquinolone derivatives via nickel‐catalyzed annulation of substituted 2‐halobenzamidines with aryl alkynes in the presence of water is described. Benzo[4,5]imidazo[2,1‐a]isoquinolines were formed as the dominated products when dry dimethyl sulfoxide was used as the solvent. Furthermore, when benzyl substituted amidines were used as the substrates

  been achieved using imines as reagents and potassium tert-butoxide as the catalyst. Depending on the solvent used, the reaction proceeds by two pathways. In THF, an addition/elimination reaction of exo-cyclic enol ethers with imines provides dihydroisobenzofuran derivatives in good yield. In DMSO, an addition/ring-opening/cyclization cascade reaction occurs with unexpected cleavage of C–O and C–C bonds

  for electrochemical radical cascade annulation of 1,2,3-benzotriazinones with alkynes is described. Under catalyst-free and external reductant-free electrolysis conditions, a range of isoquinolin-1(2H)-ones were obtained in moderate to good yields. Cyclic voltammetry and control studies suggest that the reaction proceeds via a radical pathway. Furthermore, this approach could be easily scaled up.

  Transition metal-free cascade reactions of alkynols with imines have been achieved using potassium tert-butoxide as catalyst. Switching the reaction solvent gives two kinds of products in good yield: isoquinolin-1(2H)-one derivatives and dihydroisobenzofuran derivatives. This approach was used to generate the natural product 8-oxypseudopalmatine in a two-step procedure from commercially available starting materials. Additionally, multicomponent reactions of alkynols, aldehydes, and amines were also successfully achieved to afford isoquinolin-1(2H)-one derivatives.
