Abstract: A novel, efficient, and green catalytic system under visible light irradiation has been introduced for the synthesis of anticancer biarylquinolooxazocino-quinoxaline-1-ones in one-pot sequence. The developed synthetic approach will be successfully utilized for the synthesis of various bioactive biarylquinolone in near future. Also, the cytotoxicity profile of these scaffolds has unveiled their superb cytoselectivity in HeLa and MCF-7 cell line compared to cisplatin.
