Tada! Highly functionalized chiraldibenzazepinones are obtained by a mild palladium(0)‐catalyzed enantioselective CH arylation with excellent selectivities by using simple taddol phosphoramidite ligands. The amide tether allows exclusive regioselectivity through a rare eight‐membered palladacycle intermediate.
