Abstract | An oxidative cyclization of dienic sulfonamides, e.g. I, mediated by iodobenzene diacetate in TFA, followed by a tandem intramol. Diels-Alder reaction, achieves desymmetrization of a "locally sym." dienone with good levels of diastereoselectivity and leads to valuable synthetic intermediates for the himandrine alkaloids, e.g. II.
