A novel, flexible and strong technique for the synthesis of indazolo[3,2‐ b ]quinazoline motifs using NiTiO 3 as a mild catalyst was reported. The reaction was effectively created utilizing 3,4‐dihydronaphthalen‐1(2 H )‐one ( 1a ), benzaldehyde ( 2a ) and 1 H ‐indazol‐3‐amine ( 3a ) by visible light/ultrasonic medium. Moreover, a proposed reaction pathway included Claisen–Schmidt condensation; Michael reaction with the nucleophilic endocyclic processes and oxidation for three‐component domino convention is also examined. The synthesized compounds were fluorescent in nature and have high fluorescence quantum yields.
