Ru(II)-Catalyzed and Ligand-Controlled C–H Activation and Annulation via 1,2-Phenyl Shift: Synthesis of Quaternary Carbon-Centered Pyrimidoindolones
A novel RuÂ(II)-catalyzed C–H
activation and annulation reaction
of <i>N</i>-arylpyrazol-5-ones and diaryl/arylalkyl-substituted
alkynes is developed. Unlike the reported metal-catalyzed C–H
activation and annulation reactions, in the present bidentate amine-ligand
controlled C–H activation and annulation reaction, the annulation
occurs via a 1,2-aryl shift to afford quaternary carbon-centered pyrimidoindolones
