A game of dominoes: A synthetic route to aza‐dihydrodibenzoxepines is described, through the combination of a Rh‐catalyzed arylation and a Pd‐catalyzed C‐O coupling in a single pot. For the first time, the ability to incorporate a chiral and an achiral ligand in a two‐component, two‐metal transformation is achieved, giving the products in moderate to good yields, with excellent enantioselectivities
