enantiospecific total synthesis of rhodexin A via a very hindered inverseelectrondemandDiels–Alderreaction are described. The C8-diastereomer of the fully elaborated tetracyclic core of rhodexin A, 23, was prepared in good yield and excellent selectivity using as the key step the stepwise Diels–Alderreaction of the very hindered dienone 3 and the silyl enolether 4 catalyzed by the very strong Lewis
