  • Gold-Catalyzed Cascade Reactions of Furan-ynes with External Nucleophiles Consisting of a 1,2-Rearrangement: Straightforward Synthesis of Multi-Substituted Benzo[<i>b</i>]furans
    作者:Ning Sun、Xin Xie、Yuanhong Liu
    DOI:10.1002/chem.201400112
    日期:2014.6.10
    A gold‐catalyzed cycloisomerization of silyl‐protected 2‐(1‐alkynyl)‐2‐alken‐1‐(2‐furanyl)‐1‐ols with various nucleophiles including water, alcohol, aniline, sulfonamide, and electron‐rich arene has been developed. The method provides a highly efficient access to 5,7‐disubstituted or 2,5,7‐trisubstituted benzo[b]furans with a wide diversity of substituents under mild reaction conditions, which are
    甲硅烷基保护的2-(1-炔基)-2-烯基-1-(2-呋喃基)-1-醇与各种亲核试剂(包括水,醇,苯胺,磺酰胺和富电子芳烃)的金催化环异构化反应已开发。该方法提供了以高效率的存取5,7-二取代的或2,5,7-三取代的苯并[ b ]呋喃与取代基的反应条件温和,这是不通过其他方法容易获得下一个广泛的多样性。值得注意的是,在环化过程中,烷基从呋喃环的C2到C3位置发生了有趣的重排。通过以下金辅助的烯丙基取代,可以在其C5位侧链上修饰具有广泛官能团的苯并[ b ]呋喃。
  • Gold-Catalyzed Approach to Multisubstituted Fulvenes via Cycloisomerization of Furan/Ynes
    作者:Yifeng Chen、Yuanhong Liu
    DOI:10.1021/jo2004023
    日期:2011.7.1
    A new approach to functionalized fulvenes with an enone or enal moiety has been developed through gold-catalyzed intramolecular cycloisomerization of furan/ynes with a two-carbon tether in between the furan and the triple bond. The reaction proceeds with complete regioselectivity via a 6-endo-cyclization and high stereoselectivity. Moreover, the E- or Z-stereochemistry of the double bond in fulvene products can be easily controlled by performing the reaction in different solvents.
  • One-Pot Synthesis of Indole-Fused Scaffolds via Gold-Catalyzed Tandem Annulation Reactions of 1,2-Bis(alkynyl)-2-en-1-ones with Indoles
    作者:Xin Xie、Xiangwei Du、Yifeng Chen、Yuanhong Liu
    DOI:10.1021/jo2017668
    日期:2011.11.4
    The gold-catalyzed tandem cyclization of 1,2-bis(alkynyl)-2-en-1-ones with indoles offers an efficient and straightforward route to indole-fused polycyclic systems. The process is realized through a cascade carbonyl-yne cyclization/Friedel–Crafts/indole-yne cyclization sequence catalyzed by a single-pot catalyst of gold.
    1,2-双(炔基)-2-en-1-one与吲哚的金催化串联环化为吲哚稠合的多环体系提供了一条有效而直接的途径。该过程是通过单罐金催化剂催化的羰基-炔级联/ Friedel-Crafts /吲哚-炔级联反应来实现的。
  • NHC-Catalyzed Chemoselective Reactions of Enals and Cyclopropylcarbaldehydes for Access to Chiral Dihydropyranone Derivatives
    作者:Yingling Nong、Chen Pang、Kunpeng Teng、Sheng Zhang、Qian Liu
    DOI:10.1021/acs.joc.3c01171
    日期:2023.10.6
    An N-heterocyclic carbene (NHC)-catalyzed chemoselective activation reaction of 1-cyclopropylcarbaldehydes and α-alkynyl enals is reported. NHC selectively catalyzes 1-cyclopropylaldehydes, followed by a [2 + 4] cycloaddition reaction with α-alkynyl enals. The target dihydropyranone derivatives bearing different substituents and substitution patterns can be obtained in good to excellent yields with
