  Vicarious Nucleophilic Substitution of α-Hydrogen of BODIPY and Its Extension to Direct Ethenylation

  摘要：

  Direct, oxidizer-free substitution of the 3-hydrogen of BODIPY derivatives has been established through a vicarious nucleophilic substitution procedure. This methodology has been combined with a reversible Michael addition on nitrostyrenes to provide a novel, highly efficient entry to the valuable 3-styrylated BODIPY dyes.

• An Ionic Liquid Containing L-Proline Moiety as Highly Efficient and Recyclable Chiral Organocatalyst for Michael Addition
  作者：Jiang Li、Xia Bing Li、Sha Sha Ma、Juan Liu、Ben Hao Li、Bao Lin Li

  DOI：10.1002/bkcs.10848

  日期：2016.8

  A novel chiral ionic liquid containing proline moiety was synthesized. It can be used as a highly efficient and recyclable chiral organocatalyst for Michael addition of cyclohexanone with (E)‐β‐nitroalkenes in methanol at room temperature. The Michael addition affords the corresponding products in satisfactory yields of isolated products (78–98%) with high diastereoselectivities and excellent enantioselectivities

  A mild Rh-catalyzed method was developed for the synthesis of hydroxyimino functionalized indazolo[1,2-a]cinnolines and phthalazino[2,3-a]cinnolines by reductive [4 + 2] annulation between 1-arylindazolones and 2-aryl-2,3-dihydrophthalazine-1,4-diones with varied nitroolefins. The targeted oxime decorated tetracyclic fused cinnolines were synthesized via sequential C–H activation/olefin insertion/reduction

  A range of nitro compounds are smoothly reduced to their corresponding oximes under the synergistic effects of visible light irradiation, the Ru(bpy)3Cl2 photocatalyst, Hünig’s base, Mg(ClO4)2 activation, and MeCN solvent. This remarkably mild and environmentally benign protocol, when orchestrated with classical Beckmann rearrangement, enables such high-value industrial feedstock as caprolactam to

  在可见光辐射，Ru（bpy）3 Cl 2光催化剂，Hünig碱，Mg（ClO 4）2活化和MeCN溶剂的协同作用下，一系列硝基化合物被平滑还原为相应的肟。当采用经典贝克曼重排进行编排时，这种非常温和且对环境无害的方案使得从简单的前体硝基环己烷中即可轻松获得诸如己内酰胺之类的高价值工业原料。
