A mild one-pot condensation/light-mediated cyclisationreaction leading to a diverse range of densely functionalised tetrahydroquinoline and quinoline products is described, proceeding via divergent electrocyclisation and photoredox pathways, respectively. Thorough exploration of the reaction substrate scope, reaction intermediates and mechanistic pathways uncovers the key driving forces for the observed
The development of aerobic oxidative C–H/N–H cross-coupling catalyzed by the first-row transition metals is attractive yet challenging. Here, the first iron-catalyzed intramolecular cross-dehydrogenative coupling for the synthesis of carbazoles and indoles using air as the oxidant is reported. The general and efficient protocol allows for C–Nbondformation under green conditions with excellent functional
