3. During the first total synthesis of chelidonine, a cytotoxic natural product isolated from the root of Chelidonium majus, the investigators used only heat to achieve the following transformation.? This transformation is believed to occur via two successive pericyclic processes (an electrocyclic ring- opening reaction, followed by a Diels-Alder cycloaddition). Draw the mechanism as described.
