Electrophotoredox cerium-catalyzed decarboxylative radical cyclization cascade for the synthesis of alkylated benzimidazo-fused isoquinolinones

We report an electrophotoredox cerium-catalyzed LMCT strategy to incorporate carboxylic acids into radical cyclization cascades. This protocol provides a solution to address the challenges in alkylated benzimidazo-fused isoquinolinone synthesis.
