Use of tailored boronic acids both as a radical donor and acceptor in a visible light-mediated di-functionalization of maleimides: rapid access to fused benzo[ e ]isoindole-1,3-diones

A visible light-mediated di-functionalization of maleimide with boronic acid is unveiled for synthesizing a library of benzo[ e ]isoindole-1,3-diones via a radical addition cascade cyclization (RACC) strategy.
