  Palladium-Catalyzed C-Allylation of Benzoins and an NHC-Catalyzed Three Component Coupling Derived Thereof: Compatibility of NHC- and Pd-Catalysts

  摘要：

  A large range of benzoins was successfully applied as C-nucleophiles in the palladium-catalyzed allylic alkylation with several allyl acetates, resulting in functionalized tertiary homoallylic alcohols. A number of unsymmetrical benzoins can be coupled with high levels of regio- and chemoselectivity. Finally, the challenging compatibility of free N-heterocyclic carbenes with a palladium catalyst has been utilized in a number of metal- and organocatalyzed three-component coupling reactions.

  日期：——

  Tandem catalysis: α-carbonyl homoallylic alcohols are synthesized thanks to a tandem reaction that combines the benzoin condensation of aldehydes (synthesis of α-hydroxyketones) promoted by 1,3-dimethylimidazolium chloride/DBU system and the nickel-catalyzed allylic alkylation with allylic alcohol.

  串联催化：α-羰基高烯丙醇是通过串联反应合成的，该反应结合了由 1,3-二甲基咪唑氯化物/DBU 系统促进的醛的安息香缩合（α-羟基酮的合成）和镍催化的烯丙基烷基化与烯丙醇.
