Skeletal Reorganization\nEmanated via the Course of\nHeterocyclic N<sup>1</sup>–N<sup>2</sup> Bond Cleavage: Electrosynthetic\nApproach

A unified method toward the synthesis of functionalized\ndiazepines\nand quinazolines through reorganization of the molecular skeleton\nhas been devised. The process is indulged by electrical energy via\na domino N<sup>1</sup>–N<sup>2</sup> bond cleavage followed\nby concomitant ring closing, initiating from cinnolines and indazoles\nas designed precursors. Additionally, an intermolecular ring homologation\nhas also been established to synthesize densely functionalized dihydroquinazolines\nfrom 2,3-diaryl-indazoles and acetonitrile involving the same electrochemical\nstrategy.
