  An efficient method for the one‐pot synthesis of substituted phenanthridinone derivatives from N‐methoxybenzamides and aryltriethoxysilanes through rhodium‐catalyzed dual CH bond activation and annulation reactions is described. A double‐cycle mechanism is proposed to account for this catalytic reaction. In addition, isotope‐labeling studies were performed to understand the intimate mechanism of the

  Strained alkynes include arynes and cyclooctynes reacted with N-methoxyamides through palladium-catalyzed C-H/N-H activation for the first time. A variety of important N-heterocycles such as phenanthridinones and isoquinolones were constructed in one step with high efficiency.

  Efficient annulation of benzamides with arynes using palladium and photoredox dual catalysis under an oxygen atmosphere is disclosed, which circumvents the use of external toxic metal oxidant and proceeds readily via aryne insertion at room temperature to construct the phenanthridinone backbone.
