Herein, we report a nickel-catalyzed intramolecular denitrogenative dual annulation reaction of aryl nitrile-containing 1,2,3-benzotriazine-4(3H)-ones to synthesize polycyclic pyrroloquinazolinones with a tolerance of a wide diversity of substituents. This catalytic reaction is the first denitrogenative transannulation of 1,2,3-benzotriazine-4(3H)-one with nitrile, which can be applied as the critical
在此,我们报道了含芳基腈的1,2,3-苯并三嗪-4(3 H )-酮的镍催化分子内脱氮双环化反应,合成了具有多种取代基的多环吡咯并喹唑啉酮。该催化反应是1,2,3-苯并三嗪-4(3H)-酮与腈的首次脱氮转环反应,可作为合成洛托宁A的关键步骤,具有较高的步骤经济性。
