Abstract

AbstractA visible‐light‐mediated intermolecular radical insertion of isocyanides to electron‐deficient o‐alkenylanilines leading to isoindolinone is reported. Deuterium (D2O) and H2O18 labelling experiments suggest H and O incorporation in the product. The formation of an N‐centered radical (NCR) via stepwise PT/ET process was confirmed by radical trapping experiments, photoluminescence, cyclic voltammetry and DFT studies. This photo cascade methodology is overall a redox neutral process featuring metal‐free condition and broad substrate scope (32 examples). The synthesis of analogue of GABA receptor antagonist shows the practical utility of this method.magnified image
