Visible-light induced synthesis of 8H-indolo[3,2,1-de]phenanthridin-8-ones and related heterocycles using benzothiadiazole as photocatalyst

A simple and mild approach to access polycyclic 8H-indolo[3,2,1-de]phenanthridin-8-ones through a visible-light induced free radical cyclization of (2-bromophenyl)(9H-carbazol-9-yl)methanones using benzothiadiazole-containing photocatalyst is reported. This transition metal free method can be utilized for the synthesis of 7H-thieno[2′,3′:4,5]pyrido[3,2,1-jk]carbazol-7-one, 14H-isoquinolino[4,3,2-kl]phenoxazin-14-one, 14H-isoquinolino[4,3,2-kl]phenothiazin-14-one, and 10,11,12,13-tetrahydro-8H-indolo[3,2,1-de]phenanthridin-8-one. Moreover, some products were found to emit strong blue or green fluorescence.

STUDIES ON ENAMIDES PART-2 : A NOVEL PHOTOCHEMICAL SYNTHESIS OF 9H-INDOLOPHENANTHRIDIN-9-ONE, A BENZCANTHINE ANALOGUE

The synthesis of 3-aroylcarbazoles and the unknown 1-aroylcarbazoles has been achieved by the photolysis of 9-aroylcarbazoles in polar solvent.Irradiation of 3(a-c) in non-polar solvent afforded regiospecifically 5(a-c), carbazole (1) and for the first time, 9H-indolophenanthridin-9-one (8) from 3b.The yield of 8 was significantly improved by UV exposure of 9-(2-iodobenzoyl)-carbazole (3e) in methanol and iodine, without providing any photomigrated product.
