  摘要：

  A potentially versatile route to 2-(2-aminoaryl)indoles is described based on a palladium-mediated cyclisation of N-substituted indoles, together with free radical cyclisation of their N-benzyliodoacetamide derivatives to the 7,12-dihydro-indolo[3,2-d][l]berizazepin-6(5H)-one system.

  One-Pot Synthesis of Pyrimido[1,6-a]indol-1(2H)-one Derivatives by a Nucleophilic Addition/Cu-Catalyzed N-Arylation/Pd-Catalyzed C−H Activation Sequential Process

  摘要：

  A novel and convenient one-pot synthesis of pyrimido[1,6-a]indol-1(2H)-one derivatives through a nucleophilic addition/Cu-catalyzed N-arylation/Pd-catalyzed C H activation sequential process is described. The reaction of easily prepared ortho-gem-dibromovinyl isocyanates with N-alkylanilines gave the desired indole derivatives in moderate to good yields.
