    摘要:
    在室温下,在金(I)催化剂和少量MeOH或4-甲氧基苯基硼酸的存在下,大范围的伯,仲和叔炔丙醇会进行Meyer-Schuster重排,从而得到烯酮。以该反应为关键步骤,实现了烯酮天然产物异麦角酮和达芬酮的合成。伯炔丙醇的重排可以很容易地在单锅法中结合,向所得的末端烯酮中添加亲核试剂,得到β-芳基,β-烷氧基,β-氨基或β-硫代酮。带有相邻的富电子芳基的炔丙醇也可以通过氧,氮和碳亲核试剂进行银催化的醇取代。

  • Gold-Catalyzed Hydrophenoxylation of Propargylic Alcohols and Amines: Synthesis of Phenyl Enol Ethers
    作者:Victor Laserna、Catherine Jeapes Rojas、Tom D. Sheppard
    DOI:10.1021/acs.orglett.9b01208
    日期:2019.6.21
    A practical method for the synthesis of phenyl enol ethers is reported. The combination of a gold(I) catalyst and potassium carbonate selectively mediates the addition of phenols to propargylic alcohols/amines in a chemo-, regio-, and stereoselective fashion in high yield. The resulting enol ethers are formed exclusively with a Z-configuration and can be obtained from a wide array of phenols and propargylic

  • Gold-Catalyzed Hydroamination of Propargylic Alcohols: Controlling Divergent Catalytic Reaction Pathways To Access 1,3-Amino Alcohols, 3-Hydroxyketones, or 3-Aminoketones
    作者:Victor Laserna、Michael J. Porter、Tom D. Sheppard
    DOI:10.1021/acs.joc.9b00988
    日期:2019.9.20
    Alternatively, by using a catalytic quantity of aniline, 3-hydroxyketones can be obtained in high yield directly from propargylic alcohols. Further manipulation of the reaction conditions enables the selective formation of 3-aminoketones via a rearrangement/hydroamination pathway. The utility of the new chemistry was exemplified by the one-pot synthesis of a selection of N-arylpyrrolidines and N-arylpiperidines
    据报道,有一种通用的丙炔醇增值方法,可控制从同一原料中获得三种不同的产品。首先,描述了一种使用催化以炔丙基醇加氢丙炔醇的一般方法,以产生具有完全区域选择性的3-羟基亚胺。可以将这些3-羟基亚胺还原成具有高顺式选择性的1,3-基醇。或者,通过使用催化量的苯胺,可以直接从炔丙醇以高收率获得3-羟基酮。反应条件的进一步控制使得能够经由重排/氢化胺化途径选择性地形成3-基酮。通过一锅法合成选择的N-芳基吡咯烷和N-芳基哌啶来举例说明新化学方法的实用性。
  • A Dual Gold-Iron Catalysis for a One-Pot Synthesis of 2,3-Dihydroisoxazoles from Propargylic Alcohols and N-Protected Hydroxylamines
    作者:Olivier Debleds、Christophe Dal Zotto、Emmanuel Vrancken、Jean-Marc Campagne、Pascal Retailleau
    DOI:10.1002/adsc.200900127
    日期:——
    A concise one-pot route for the synthesis of 2,3-dihydroisoxazoles via a dual gold-iron catalysis has been devised. The method, based on the addition of binucleophilic protected hydroxylamine to propargylic alcohols, enables a one-pot, highly selective synthesis of these heterocycles (10 examples, up to 86% yield).

  • Studies on Pd(II)-Catalyzed Synthesis of (<i>Z</i>)-α-Haloalkylidene-β-lactones from Cyclocarbonylation of 2-Alkynols and the Subsequent Coupling Reactions
    作者:Shengming Ma、Bin Wu、Xuefeng Jiang、Shimin Zhao
    DOI:10.1021/jo0480038
    日期:2005.4.1
    A good regio- and stereoselectivity was observed for the PdCl2-catalyzed cyclocarbonylation of 2-alkynols with CuCl2 affording (Z)-alpha-chloroalkylidene-beta-lactons. The highly optically active (Z)-alpha-chloroalkylidene-beta-lactones could be easily prepared from the readily available optically active propargylic alcohols. The Pd(II)-catalyzed cyclocarbonylation of 2-alkynols with CuBr2 was also studied. Although the yields of (Z)-alpha-bromoalkylidene-beta-lactones were low, due to the relatively higher activity of the C-Br bond, the coupling reactions of (Z)-alpha-bromoalkylidene-beta-lactones were quite smooth to afford the corresponding products in high yields. A rationale for this reaction is discussed.
  • Regioselective Rapid Synthesis of Fully Substituted 1,2,3-Triazoles Mediated by Propargyl Cations
    作者:Huan Zhang、Hiroki Tanimoto、Tsumoru Morimoto、Yasuhiro Nishiyama、Kiyomi Kakiuchi
    DOI:10.1021/ol402387w
    日期:2013.10.18
    Regioselective rapid triazole syntheses at low temperature are described. Organic azides and propargyl cations generated by acids gave fully substituted 1H-1,2,3-triazoles. Most reactions could be performed in 5 min at not only rt but also -90 degrees C. Both terminal and internal alkynes were acceptable, and the sterically bulky substituents could afford the products smoothly. Various types of three-component coupling reactions were demonstrated, and the presence of allenylaminodiazonium intermediates was indicated.
