Article Synopsis
  • The study explores a metal-free method for activating oxygen on benzylamine/alcohols using quaternary alkylammonium-based ionic liquids, which produce various organic compounds without transition metals.
  • NMR and control experiments confirm the reaction mechanism, where molecular oxygen is converted into a hydroperoxyl radical, with the formation of hydrogen peroxide supporting this process.
  • Advanced computational methods, such as DFT and DLPNO-CCSD(T), confirm that the ionic liquids enhance oxygen activation, suggesting a cost-effective and efficient alternative to traditional metal catalysts in organic synthesis.

Herein, a one-pot protocol to synthesize tetracyclic triazole-piperazine-quinazolinone-fused N-heterocyclic scaffolds is reported. In this strategy, a tandem approach of two highly efficient synthetic reactions, click and cross-dehydrogentive coupling reactions, with high atom economy were employed to obtain the target N-fused scaffolds. Being highly functional group tolerable, this method has broad substrate scope.
