A rapid entry towards the Podophyllum lignans is described exemplified by a concise regioselective total synthesis of taiwanin E 5 and chinensinaphthol 6. The approach features a Michael Initiated Ring Closure (MIRC type II) sequence to access the key lignan intermediates 11a & b from the ketodithianes 10a & b and 2-(5H)-furanone.
