  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.

  The present invention relates to the field of catalytic hydrogenation and, more particularly, to the use of specific ruthenium catalysts, or pre-catalysts, in hydrogenation processes for the reduction of ketones and/or aldehydes into the corresponding alcohol respectively. Said catalysts are ruthenium complexes comprising a tetradentate ligand (L4) coordinating the ruthenium with: - two nitrogen atoms, each in the form of a primary or secondary amine (i.e. a NH2 or NH group) or N-alkyl imine functional groups (i.e. a C=N group), and - two sulfur atoms, each in the form of thioether functional groups.

  本发明涉及催化加氢领域，更具体地涉及在氢化过程中使用特定的钌催化剂或前驱体，用于将酮和/或醛还原为相应的醇。所述催化剂是包含四齿配体（L4）的钌络合物，该配体与钌配位，其中：- 两个氮原子，每个以主要或次要胺（即NH2或NH基团）或N-烷基亚胺官能团（即C=N基团）的形式存在，以及- 两个硫原子，每个以硫醚官能团的形式存在。
