Regio- and Diastereoselective Radical Dimerization Reactions for the Construction of Benzo[ f ]isoindole Dimers.

This study presents a novel approach for synthesizing benzo[ f ]isoindole dimers, which involves cascade cyclization and oxidative radical dimerization. Our method allows for the formation of up to five carbon-carbon bonds in a single reaction, exhibiting remarkable diastereoselectivity and regioselectivity. The mechanism and regioselectivity were investigated through a combination of experiments and calculations.
