An account of our previously disclosed total synthesis of the aryltetralinlignan natural product podophyllotoxin, a building block used in the synthesis of the FDA-approved anticancer drug etoposide, is disclosed. A C–H activation disconnection was viewed as being amenable to the preparation of E-ring modified analogs but proved challenging to execute. Various insights into palladium-catalyzed C–H
