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 lig

2-(2-Dithianyl)benzhydrols (2 a-c) undergo facile cycloaddition reaction with maleic anhydride under thermal conditions to give 1-phenyl-naphthalenes (7 a-c) in one step.The naphthalenes (7 a-c) have been converted into the naphthalene lignan lactones, (9 a-c) and (10 a-c).
