AbstractWe herein report the first total synthesis of the dibenzocycloheptanoide (±)‐dihydroisosubamol. The key step includes a recently developed gold‐catalysed hydroarylation reaction for the construction of the dibenzocycloheptene motif. Additional steps are a Suzuki‐Miyaura cross coupling, a palladium‐catalysed hydroxylation and an allylic oxidation. To access the saturated seven‐membered ring system an iridium‐catalysed hydrogenation proved to be successful.magnified image
