  A General and Facile Synthesis of Substituted Furans by Palladium-Catalyzed Cycloisomerization of (Z)-2-En-4-yn-1-ols

  摘要：

  A general and facile synthesis of furans, based on Pd(II)-catalyzed cycloisomerization of (Z)-2-en-4-yn-1-ols, is described. Cycloisomerization reactions are carried out at 25-100 degrees C in the presence of a very simple catalytic system, consisting of K2PdI4, under essentially neutral conditions. This new methodology is very versatile and can be applied to the synthesis of a variety of substituted furans, including particularly fragile, naturally occurring furans such as rosefuran. Efficient synthetic approaches for the regioselective synthesis of suitably substituted (Z)-2-en-4-yn-1-ols have been developed.

• General and Regioselective Synthesis of Substituted Pyrroles by Metal-Catalyzed or Spontaneous Cycloisomerization of (<i>Z</i>)-(2-En-4-ynyl)amines

  A general and regioselective synthesis of substituted pyrroles 2 by cycloisomerization of readily available (Z)-(2-en-4-ynyl)amines 1 is reported. Spontaneous cycloisomerization leading to 2 occurred in the course of preparation of enynamines bearing a terminal triple bond or a triple bond substituted with a phenyl or a CH2OTHP group. When the triple bond was substituted with an alkyl or alkenyl group

  据报道，通过容易获得的（Z）-（2-en-4-炔基）胺1的环异构化，一般和区域选择性地合成取代的吡咯2。在制备带有末端三键或被苯基或CH 2 OTHP基团取代的三键的烯胺的过程中发生自发的环异构化反应，导致2。当三键被烷基或烯基取代时，烯胺是稳定的并且可以通过金属催化转化为相应的吡咯。发现CuCl2是用于在C-3处取代的底物进行环异构化的出色催化剂，而PdX2与KX（X = Cl，I）结合使用则是在C-3处未取代的烯胺反应的优良催化剂。

  (Z)-(2-En-4-ynyl)amines 1 bearing an internal triple bond undergo smooth cycloisomerization into pyrroles 2 in the presence of catalytic amounts of PdCl2 in conjunction with KCl at 25–100°C in anhydrous N,N-dimethylacetamide. When the triple bond is terminal, spontaneous uncatalyzed cyclization to the corresponding pyrroles takes place.

• An Efficient and General Synthesis of Furan-2-acetic Esters by Palladium-Catalyzed Oxidative Carbonylation of (<i>Z</i>)-2-En-4-yn-1-ols

  日期：1999.10.1

  A variety of (Z)-2-en-4-yn-1-ols have been carbonylated under oxidative conditions to give substituted furan-a-acetic esters in good yields. The cyclization-alkoxycarbonylation process occurs in alcoholic media at 50-70 degrees C and under 100 atm pressure of a 9:1 mixture of carbon monoxide and air in the presence of catalytic amounts of PdI2 in conjunction with KI. The proposed reaction pathway involves the in situ isomerization of the initially formed (E)-2-[(alkoxycarbonyl)methylene]-2,5-dihydrofuran species, which in some cases have been isolated and shown to be the intermediates.
