Molecular intelligence: The structurally novel lignan (+)‐linoxepin is synthesized in an eight‐step sequence. The enantioselective synthesis features the palladium‐catalyzed Catellani reaction as the key step. In this highly convergent multicomponent reaction, two new carbon–carbon bonds are formed, one of which results from a CH bond functionalization.
