    Synthesis of 4-Ynamides and Cyclization by the Vilsmeier Reagent to Dihydrofuran-2(3H)-ones
    摘要:
    The room-temperature nucleophilic addition of vinyl azides to propargylic alcohols under BF3 center dot Et2O catalysis provides an efficient synthesis of 4-ynamides. The procedure is operationally convenient, shows broad substrate scope, and is viable for the synthesis of multifunctional 4-ynamides. Further, a Vilsmeier intramolecular cyclization of 4-ynamides into dihydrofuran-2(3H)-ones has also been discovered, which represents the first report of alkynes being used as the nucleophiles in Vilsmeier-type reactions.

    日期:2020.7
    A simple protocol to synthesize indenes efficiently by PTSA catalyzed tandem Friedel–Crafts alkylation/hydroarylation of tertiary propargylic alcohol with electron-rich arenes is described. The desired indenes were obtained regioselectively in good to very good yields under mild reaction conditions. The allene intermediate was isolated to get an insight into the mechanistic pathway of the indene forming

  • Palladium(II)/N-Heterocyclic Carbene-Catalyzed Regioselective Heteroannulation of Tertiary Propargyl Alcohols and<i>o</i>-Haloanilines to form 2-Alkenylindoles
    作者:Pradeep Kumar Reddy Panyam、Thirumanavelan Gandhi

    日期:2017.4.3
    Monometallic and bimetallic palladium(II)/N‐heterocyclic carbene complexes appended with naphthalimide or bisnaphthalimide moieties were designed, synthesized, and characterized. Employment of these catalysts brings about the step‐economic and regioselective heteroannulation of tertiary propargyl alcohols with o‐haloanilines resulting in biologically and pharmaceutically relevant 2‐alkenylindoles.

    设计,合成和表征了单金属和双金属钯(II)/ N-杂环卡宾配合物,并附加了萘二甲酰亚胺或双萘二甲酰亚胺部分。这些催化剂的使用带来了叔炔丙醇与邻卤代苯胺的逐步经济和区域选择性杂成环化反应,从而产生了生物学上和药学上相关的2-烯基吲哚。通过在插入过程中炔丙基羟基部分与钯的配位,无法阐明区域选择性杂环化的基础。采用这种方法,可以通过后期修饰获得不对称的2,3-二取代吲哚的单一区域异构体。已经研究了将萘二甲酰亚胺或双萘二甲酰亚胺附加到NHC上对催化效率的作用。

    A nucleophilic substitution of propargylic alcohols with carbon (arene, heteroarene, and allyltrimethylsilane), sulfur (thiol), oxygen (alcohol), and nitrogen (sulfonamide) nucleophiles has been demonstrated using a high-valent [Ir(COD)(SnCl3)Cl(μ-Cl)]2 catalyst in 1,2-dichloroethane to afford the corresponding propargylic products in moderate to excellent yields.
