    将金催化的环异构化外推到钯催化的炔醇交叉偶联/环异构化以合成多取代呋喃:串联过程的范围和应用
    摘要:
    摘要 本文描述了通过金和钯催化的 π 活化化学从炔醇制备多种呋喃衍生物的综合方法的发展。值得注意的是,发现这种新方法适用于含环辛基的底物,与我们之前的报告相比,这代表了对该方法的显着扩展。此外,这种新开发的方法允许在 Sonogashira 条件下从其合成前体直接构建环辛基呋喃。实验结果表明,钯在这些反应中起两个主要作用,包括(1)底物交叉偶联反应中必不可少的催化剂;(2) 通过典型的 π 活化过程促进炔醇中间体的环化。3-碘呋喃的一锅合成强调了这种化学的范围,这为进一步功能化(通过偶联方法)提供了机会。最后,AuBr 3 协议还详细阐述了多米诺环化/C-H 活化反应,以及无环前体的环化。总之,这项研究的结果表明,金和钯催化剂可用于在环化反应中相互补充。

  • Copper/P(<i>t</i> Bu)<sub>3</sub> -Mediated Regiospecific Synthesis of Fused Furans and Naphthofurans
    作者:Togati Naveen、Arghya Deb、Debabrata Maiti

    日期:2017.1.19
    to construct substituted fused furans and naphthofurans from readily available starting materials under mild reaction conditions. The utility of the method is further demonstrated by the synthesis of chiral furans from (R)‐()‐carvone and (S)‐(+)‐carvone. A plausible mechanism involving the oxidative radical cyclization has been suggested based on experimental observations.

However, a facile cycloisomerization in the presence of cationic complexes, as well as observed migratory aptitude in the cycloisomerization of unsymmetrically disubstituted aryl- and alkylallenes, strongly supports electrophilic nature for this transformation.
