摘要
Herein, we demonstrate a regioselective intramolecular C-N cross-coupling for the synthesis of 14-quinazolino[3,2-]phenanthridin-14-one by using 9-mesityl-10-methylacridinium perchlorate as the visible-light (450-470 nm) photocatalyst. The experiments with BHT, TEMPO, and Stern-Volmer quenching studies helped to rationalize a radical pathway a SET mechanism.
