    摘要:
    Abstractmagnified imageDescribed herein is the development of a palladium(II)‐catalyzed two‐ or three‐component reaction of 2‐(1‐alkynyl)‐2‐alken‐1‐ones with nucleophiles and allylic chlorides. Various types of nucleophiles such as O‐, N‐, C‐based nucleophiles and olefin‐tethered O‐, N‐, C‐based nucleophiles were investigated. The scope, mechanism and application of this Pd(II)‐catalyzed domino reaction were studied. In these transformations, the palladium catalyst exhibits a dual role, serving simultaneously as a Lewis acid and a transition metal. Two possible reaction pathways (cross‐coupling reaction vs. Heck reaction) from the same intermediate furanylpalladium species were observed. The reaction pathway is dependent on the property of the nucleophile and the length of the tethered chain as well. When olefin‐tethered O‐based nucleophiles were used, only the cross‐coupling reaction pathway was observed, in contrast, both reaction pathways were observed when olefin‐tethered C‐based nucleophiles were employed. The product ratio is dependent on the length of the tethered chain. Furthermore, ring‐closing metathesis (RCM) of corresponding furans with CC bonds provides an easy method for the preparation of functionalized oxygen‐heterocycles – 3,4‐fused bicyclic furans. It is also noteworthy that allylic chloride can be as an oxidant besides its well known function as an alkylating reagent.

  • Cu(I) Catalyst in DMF:  An Efficient Catalytic System for the Synthesis of Furans from 2-(1-Alkynyl)-2-alken-1-ones

    The cyclization of 2-(1-alkynyl)-2-alken-1-ones 1 proceeded very smoothly in the presence of alcohols 2 with a catalytic amount of Cu(I)Br in DMF at 80 °C, leading to the formation of highly substituted furans 3. The catalytic system reported herein is easy to handle, compared to the previously known system wherein the reaction between 1 and 2 needed to use moisture sensitive gold(III) chloride.
