  Oxidative ipso-Rearrangement Performed by a Hypervalent Iodine Reagent and Its Application

  摘要：

  An oxidative ipso-rearrangement mediated by a hypervalent iodine reagent that enables rapid generation of a functionalized dienone system containing a quaternary carbon center connected to several sp(2) centers has been developed. The process occurs through transfer of an aryl group from a silyl segment present on the lateral chain. As an illustration of the potential of this transformation, a total synthesis of sceletenone, a small alkaloid, is described.

  numerous natural products. As an illustration of the potential of this transformation, total syntheses of compounds belonging to the Amaryllidaceae alkaloids family such as O-methyljoubertiamine, mesembrine, and its natural derivative the dihydro-O-methylsceletenone have been achieved in eight/nine steps. The synthetic route to these molecules features a novel and efficient transformation on the basis
