  • Palladium(0)-catalyzed Domino C−N Coupling/Hydroamination/C−H Arylation: Efficient Synthesis of Benzothieno[2′,3′:4,5]pyrrolo[1,2-<i>f</i>]phenanthridines

    efficient routes to benzothieno[2′,3′:4,5]pyrrolo[1,2‐f]phenanthridines have been developed. Alkynylated benzothiophenes reacted with various anilines to the target compounds in a domino reaction consisting of a C−N coupling‐, hydroamination‐ followed by a final, ring‐closing C−H arylation step. Products were isolated in moderate to good yields.

    palladium-catalyzed reaction of 2-alkynyl-3-bromothiophenes with anilines afforded thienopyrroles by a domino CN coupling/hydroamination process, the reaction of 2-alkynyl-3-bromobenzothiophenes with anilines resulted, under identical conditions, in the formation of benzothienoquinolines by a domino CN coupling/annulation process. The electronic character of the aniline also has an influence on the product distribution

  • Pd-Catalyzed Cascade Crossover Annulation of <i>o</i>-Alkynylarylhalides and Diarylacetylenes Leading to Dibenzo[<i>a</i>,<i>e</i>]pentalenes
    作者:Jian Zhao、Kazuaki Oniwa、Naoki Asao、Yoshinori Yamamoto、Tienan Jin

    日期:2013.7.17
    A novel and selective Pd-catalyzed cascade crossover-annulation of o-alkynylarylhalides and diarylacetylenes for the synthesis of dibenzo[a,e]pentalenes has been reported. Various arylacetylenes with a wide range of functional groups were tolerated, producing the corresponding multisubstituted dibenzopentalenes with the different substituents on the aromatic rings in good to high yields under the optimized reaction conditions. The reaction proceeds through a Pd-catalyzed cascade carbopalladation and C-H activation. The use of the combined DBU and CsOPiv bases is crucial for the successful implementation of the present cross-annulation.

    heterocyclic benzoin derivatives were prepared by Sonogashira coupling of alkynes with 1,2-dihaloalkenes and subsequent oxidation of the alkyne to a 1,2-diketone. The Pd-catalyzed reaction of the product with (2-bromophenyl)boronic acid in the presence of phenylacetylene resulted in formation of cyclic benzoin derivatives by Suzuki-Miyaura reaction and subsequent Pd catalyzed nucleophilic addition
