The first example of a copper-catalyzed halogen-free protocol to construct indazolo[3,2-b]quinazolinones was developed through sequential inert C-O bond cleavage followed by intramolecular C-N bond formation. This protocol represents an efficient synthetic tool for accessing a more diverse range of functionalized indazolo[3,2-b]quinazolinones. The structure of the newly synthesized indazolo[3,2-b]quinazolinones was unambiguously confirmed by X-ray crystal diffraction analysis.

A one-pot cascade reaction has been developed leading to the concurrent construction of six and five membered fused N-heterocyclic rings of indazolo[3,2-b]quinazolinones. The methodology involved the reaction of isatoic anhydride, a hydrazine and o-iodo b
