Facile and Mild Access to Fluorescent Ladder-Type Indolo[3,2-a]carbazoles via Cascade Annulation

Abstract A set of fluorescent ladder-type indolo[3,2- a ]carbazoles were rationally developed via cascade annulation of indoles and nitroolefins under mild reaction conditions. Diverse functional groups were tolerated. Moreover, structure–photophysical properties relationships (SPPR) of indolo[3,2-...

Zusammenfassung:Abstract A set of fluorescent ladder-type indolo[3,2- a ]carbazoles were rationally developed via cascade annulation of indoles and nitroolefins under mild reaction conditions. Diverse functional groups were tolerated. Moreover, structure–photophysical properties relationships (SPPR) of indolo[3,2- a ]carbazoles were observed to be simply tuned by changing the electronic nature of the peripheral substituents.
