    摘要:
    四环骨架的咪唑并[1,2结合一个]吡啶部分具有喹啉骨架,如吡啶并[2',1':2,3]咪唑并[4,5- b ]喹啉的刺激增加利益,因为它们是靠近电子等排物一系列强大的抗增殖化合物。在本文中,我们报告了一种通过市售或易于获得的2-氨基吡啶的一锅顺序反应合成吡啶并[2',1':2,3]咪唑并[4,5- c ]喹啉的新颖方法, 2-溴代苯甲基溴化物,氨水和醛。此外,二氢吡啶并[2',1':2,3]咪唑[4,5‐ c通过使用各种酮代替醛作为底物,也可以类似的方式获得]喹啉。值得注意的是,整个过程在一个罐中结合了缩合/胺化/环化反应,从而以一种简单而实用的方式得到了复杂的化合物。与文献方法相比,本文报道的合成策略具有以下优势:容易获得的起始原料,产物的结构多样性,良好的官能团耐受性和避免逐步操作的优点。

    日期:2020.10.2
    An efficient three-component domino or one-pot strategy has been developed for the synthesis of medicinally important benzothiophene and benzothiopheno[2,3-e]azepinedione derivatives for the first time. Amine-promoted selective cleavage of C–S bond of thioisatin is the key step in this process. The reported methodology benefits from environmentally friendly solvent (H2O), wide substrate scope, good

  • Electronic Tuning in C1-Symmetric Chelating Diphosphane Ligands Supported on Stereogenic Aryl-Heteroaryl Templates
    作者:Franco Sannicolò、Tiziana Benincori、Simona Rizzo、Serafino Gladiali、Sonia Pulacchini、Gianni Zotti
    DOI:10.1055/s-2001-18429
    日期:——
    The syntheses of a wide range of novel C 1-symmetric chelating diphosphanes with stereogenic axes are reported. These ligands feature identical or different phosphanyl groups supported on diverse atropisomeric templates based on the interconnection of five-membered heteroaromatic and six-membered carbocyclic rings. Easy synthetic accessibility, independent tunability of the electronic and steric properties of the two phosphane donors, the low cost and the good stereoselection ability of some of them obtained in an enantiopure state are the main advantageous features of this class of ligands.

  • Base-Catalyzed Synthesis of Substituted Indazoles under Mild, Transition-Metal-Free Conditions
    作者:Isabelle Thomé、Claire Besson、Tillmann Kleine、Carsten Bolm
    DOI:10.1002/anie.201300917
    日期:2013.7.15
    Back to basics: A transition‐metal‐free method developed for the synthesis of indazoles involves an inexpensive catalytic system composed of a diamine and K2CO3. Various (Z)‐2‐bromoacetophenone tosylhydrazones were converted into indazoles at room temperature in excellent yields (see example; Ts=p‐toluenesulfonyl). The yield was improved by photoisomerization with UV light when E/Z isomeric mixtures

    A practical and environmentally friendly synthesis of 3-aminomethyl-N-tosyl-indazoles is developed. The in situ formed vinyl azines are reacted with amines to furnish amino functionalized anti-hydrazones in excellent yields. Subsequent copper-catalyzed cyclization at ambient temperature is effective and desired compounds are obtained in short reaction times. Also, the formation of bisindazoles is presented for the first time. (C) 2010 Elsevier Ltd. All rights reserved.
