high reduction potential of carbonyl compounds and imines. In the context of photoredox catalysis, tertiary amines are commonly employed as sacrificial co‐reducing agents. Herein, an additional role of the amine is proposed, in which it is essential for the organocatalytic substrate activation. The combination of photoredox catalysis and carbonyl/imine activation enables the reductivecoupling of aldehydes

Copper-catalyzed coupling of imines, dienylstannanes, and acryloyl chlorides followed by a Diels−Alderreaction afforded hexahydro-1H-isoindolones. Diversification of the core via Pd-catalyzed cross-coupling defines a new modular approach to isoindolone combinatorial libraries.
