  CuH-Catalyzed Synthesis of 3-Hydroxyindolines and 2-Aryl-3H-indol-3-ones from o-Alkynylnitroarenes, Using Nitro as Both the Nitrogen and Oxygen Source

  摘要：

  CuH-catalyzed diasterospecific synthesis of 3-hydroxyindolines and 2-aryl-3H-indol-3-ones have been developed from o-alkynylnitroarenes in the presence of hydrosilane as the reductant. The protocol employs nitro as both nitrogen and oxygen sources for the intramolecular simultaneous construction of C-N and C-O bonds.

  Efficient Nucleophilic Aromatic Substitution between Aryl Nitrofluorides and Alkynes

  摘要：

  The nucleophilic aromatic substitution reaction between electron-deficient aryl fluorides and terminal alkynes is shown to be efficiently promoted by sodium bis(trimethylsilyl)amide as a base. Moderate to excellent yields of 2-ethynylnitrobenzene products can be obtained under mild conditions.

  Presented herein is a one-pot cascade reaction of o-alkynylnitrobenzenes with maleimides leading to the formation of hydroxysuccinimide substituted indolin-3-ones under Au(III)–Cu(II) relay/synergetic catalysis. Mechanistically, the formation of the title products involves an unprecedented cascade process including (1) nitro–alkyne cycloisomerization of o-alkynylnitrobenzene to give isatogen; (2) [3

  本文介绍的是邻炔基硝基苯与马来酰亚胺在 Au(III)-Cu(II) 中继/协同催化下形成羟基琥珀酰亚胺取代的 indolin-3- one 的一锅级联反应。从机理上讲，标题产物的形成涉及前所未有的级联过程，包括 (1) o的硝基-炔烃环异构化-炔基硝基苯，得到等离子；(2) isatogen与马来酰亚胺的[3+2]偶极环加成；(3)原位形成的异恶唑烷部分在中性条件下开环。值得注意的是，具有各种官能团的多种底物与反应条件相容，可以得到一系列高价值的杂化化合物，具有良好的效率和优异的原子经济性。此外，由此获得的产物可以很容易地转化为相应的马来酰亚胺取代的二氢吲哚-3-酮。重要的是，一些产品在人类癌细胞系中表现出显着的抗增殖活性。

  Rh(III)-catalyzed C7-alkylation of isatogens (indolin-3-one N-oxides) with malonic acid diazoesters has been developed. This strategy utilizes oxygen anion on the N-oxide group of isatogens as a directing group and successfully achieves the synthesis of a series of C7-alkylated isatogens with moderate to good yields (48–86% yields). Moreover, the N-oxides of isatogens can not only serve as the simple
