  Oxidative Intramolecular Phenolic Coupling Reaction Induced by a Hypervalent Iodine(III) Reagent:  Leading to Galanthamine-Type Amaryllidaceae Alkaloids

  摘要：

  By extending our oxidative phenol-coupling reactions using a hypervalent iodine(III) reagent, a versatile synthetic procedure for the galanthamine-type Amaryllidaceae alkaloids was accomplished. The first total synthesis of (+/-)-sanguinine and the total syntheses of (+/-)-galanthamine, (+/-)-narwedine, (+/-)-lycoramine, and (+/-)-norgalanthamine were also successfully carried out.
