Exploring the ring-opening reactions of imidazo[1,5-a]quinolines for the synthesis of imides under photochemical conditions.

The ring-opening reaction of imidazo[1,5-a]quinolines under photoredox conditions has been described. With Eosin Y as the organophotoredox catalyst, synthetically useful and medicinally important imides were obtained in moderate to excellent yields under mild reaction conditions.
