Indolo[2,1-b]quinazolin-12(6H)-one derivatives are prevalent in many synthetic intermediates,
pharmaceuticals, and organic materials. Herein, we developed a photoredox radical
cascade cyclization reaction that uses visible light as the primary energy input to
promote the reaction, leading to a series of indolo[2,1-b]quinazolin-12(6H)-one derivatives
under oxygen conditions.
Key words
photoredox - radical cyclization - molecular oxygen - indolo[2,1-b]quinazolin-12(6H)-one
derivatives - metal-free
