  Solvent/Oxidant-Switchable Synthesis of Multisubstituted Quinazolines and Benzimidazoles via Metal-Free Selective Oxidative Annulation of Arylamidines

  摘要：

  A fast and simple divergent synthesis of multisubstituted quinazolines and benzimidazoles was developed from readily available amidines, via iodine(III)-promoted oxidative C(sp(3))-C(sp(2)) and C(sp(2))-N bond formation in nonpolar and polar solvents, respectively. Further selective synthesis of quinazolines in polar solvent was realized by TEMPO-catalyzed sp(3)C-H/sp(2)C-H direct coupling of the amidine with K2S2O8 as the oxidant. No metal, base, or other additives were needed.

  A novel efficient method for the selective synthesis of 2-substituted benzimidazoles is described through condensation reaction of o-phenylenediamines with a wide rang of aliphatic, aromatic and heteroaromatic aldehyde substrates using Brönsted acidic ionic liquid as a reusable catalyst under metal-free conditions at ambient temperature. Notably, Dodecylimidazolium hydrogen sulfate ([DodecIm][HSO4])

  描述了一种新的有效的选择性合成2-取代的苯并咪唑的有效方法，该方法通过邻苯二胺与多种脂族，芳族和杂芳族醛底物的缩合反应，使用布朗斯台德酸性离子液体作为可重复使用的催化剂，在室温下于无金属条件下进行温度。值得注意的是，十二烷基咪唑硫酸氢盐（[DodecIm] [HSO 4 ]）是最有效的催化剂，其相应产品的产率高至优异（高达98％）。随后，该协议成功地应用于用于制备Ñ烷基化1,2-二取代的苯并咪唑在高以优异的产率通过顺序一锅反应。另外，催化剂被循环至少四次而没有明显的活性损失。

  utilized as complementary precursors for the synthesis of important heterocycles. The synthesis of N-substituted benzimidazoles was possible from the palladium-catalyzed reaction of both classes of substrate with a variety of N-nucleophiles. The use of the imidate precursor for the synthesis of N-substituted quinazolinones by incorporation of a palladium-catalyzed aminocarbonylation reaction has also been

  N-（邻卤代苯基）亚氨基酰氯和相应的酰亚胺化物易于制备，并且可用作合成重要杂环的互补前体。N-取代的苯并咪唑的合成可能是由两类底物与多种N-亲核试剂的钯催化反应所致。还已经证明了亚氨酸酯前体通过掺入钯催化的氨基羰基化反应用于合成N-取代的喹唑啉酮的用途。两种方法都可以耐受各种官能团。

  2-(2-Furyl)-1H-benzimidazoles 3-11 were synthesized and tested for their in vitro VEGF inhibition in MCF-7 cancer cell line. Compound 5a was more potent than Tamoxifen, and compounds 3b, 5a, 5c, 6b, 7a and 10 showed promising potency. Furthermore, compounds (6b, 7a and 10) showed remarkable selective inhibition of COX-2 enzyme close to that of Celecoxcib. Additionally, docking studies were performed using AutoDock 4.2 into the VEGFR2 kinase. Significant correlation exists between the biological activity (IC50 and %VEGF inhibition) against MCF-7 cell line and the molecular docking results (K-i and Delta G(b)) with correlation coefficients (R-2) of 0.5513 and 0.4623 respectively. Accordingly, most of the synthesized 2-(2-furyl)-1H-benzimidazoles showed strong antiangiogenic activity against VEGFR2 kinase. (c) 2014 Elsevier Masson SAS. All rights reserved.

  An efficient method for the transformation of N-benzyl bisarylhydrazones and bisaryloxime ethers to functionalized 2-aryl-N-benzylbenzimidazoles and 2-arylbenzoxazoles is described. The protocol involves a copper(II)-mediated cascade C-H functionalization/C-N/C-O bond formation under neutral conditions. Substrates having either electron-donating or -withdrawing substituents undergo the cyclization to afford the target heterocycles at moderate temperature.
