copper‐catalyzed domino method for synthesis of isoquinolino[2,3‐a]quinazolinones has been developed using readily available, substituted methyl 2‐(2‐haloobenzamido)benzoates and nitriles as the starting materials. The domino process comprises an Ullmann‐type C‐arylation, intramolecular addition of NH with CN, and nucleophilic attack of amino to ester group. The inexpensive, convenient and efficient copper‐catalyzed
