The first metal-catalyzed double aryl C(sp2)-H bond activation of antipyrine and alkyne annulation reaction is reported. This Ru(II)-catalyzed reaction was accomplished in the presence of 20 mol % phosphine ligand tricyclohexylphosphine tetrafluoroborate to afford indolo[2,1-a]isoquinolines that are very important compounds because of their bioactivity and interesting optical properties.
报告了安替比林和炔烃环化反应的第一个金属催化的双芳基C(sp2)-H键活化。该Ru(II)催化的反应在20mol%膦配体三环己基膦四氟硼酸酯的存在下完成,从而得到吲哚[2,1-a]异喹啉,由于它们的生物活性和令人感兴趣的光学性质,它们是非常重要的化合物。
