Palladiumcatalysed intramolecular guanidine transfer to alkenes can be accomplished with copper chloride as the oxidant to give bicyclic guanidines with complete selectivity and in high yields.
钯催化的分子内胍向烯烃的转移可以用氯化铜作为氧化剂完成,从而以完全的选择性和高收率得到双环胍。
Enantioselective Diamination with Novel Chiral Hypervalent Iodine Catalysts
chemistry because of its wide occurrence in a variety of biological and pharmaceutical molecules. We report an efficient metal‐free, highly stereoselective intramolecular diamination using a novel chiral hypervalentiodine reagent together with its application as an efficient catalyst for the synthesis of diamines.
