  • A General and Highly Selective Palladium‐Catalyzed Hydroamidation of 1,3‐Diynes
    作者:Jiawang Liu、Carolin Schneider、Ji Yang、Zhihong Wei、Haijun Jiao、Robert Franke、Ralf Jackstell、Matthias Beller

    日期:2021.1.4
    3‐diynes is described. Key for the success of this novel transformation is the utilization of an advanced palladium catalyst system with the specific ligand Neolephos. The synthetic value of this general approach to synthetically useful α‐alkynyl‐α, β‐unsaturated amides is showcased by diversification of several structurally complex molecules and marketed drugs. Control experiments and density‐functional
    描述了(不)对称 1,3-二炔的化学选择性、区域选择性和立体选择性单氢酰胺化。这种新型转化成功的关键是采用具有特定配体 Neolephos 的先进钯催化剂系统。这种合成有用的 α-炔基-α, β-不饱和酰胺的通用方法的合成价值通过几种结构复杂的分子和上市药物的多样化得到了展示。控制实验和密度泛函理论 (M06L-SMD) 计算也表明底物在控制不对称 1,3-二炔的区域选择性中发挥着关键作用。
  • α-Acyliminium ion-acetylene cyclisations

    日期:1980.1
    Cyclisation of acetylenic ethoxylactams 1b-12b leads to bridgehead nitrogen bicyclic ketones in excellent yields. The reaction is weakly acid-catalysed and proceeds at ambient temperature. The observed regioselectivity effect is discussed in terms of stability of exo vs endo vinyl cations and ring strain effects. The high yield conversion of N-(5-hexynyl)-ethoxy lactams 7b and 8b in the 5/8 and 6/8
    炔基乙氧基内酰胺1b-12b的环化可产生极高收率的桥头氮双环酮。该反应是弱酸催化的,并在环境温度下进行。根据外型对内乙烯基阳离子的稳定性和环应变效应,讨论了观察到的区域选择性效应。在5/8和6/8稠合的双环酮内酰胺7c和8c中N-(5-己炔基)-乙氧基内酰胺7b和8b的高产率转化值得特别注意。
  • Heteroaryl-substituted amides comprising an unsaturated or cyclic linker group, and their use as pharmaceuticals
    申请人:Sanofi-Aventis Deutschland GmbH
    公开号:EP1741708A1
    公开(公告)日:2007-01-10
    The present invention relates to N-alkylamides of the formula I, in which A, Het, X, R1, R2 and R3 have the meanings indicated in the claims, which modulate the transcription of endothelial nitric oxide (NO) synthase and are valuable pharmacologically active compounds. Specifically, the compounds of the formula I upregulate the expression of the enzyme endothelial NO synthase and can be applied in conditions in which an increased expression of said enzyme or an increased NO level or the normalization of a decreased NO level is desired. The invention further relates to processes for the preparation of compounds of the formula I, to pharmaceutical compositions comprising them, and to the use of compounds of the formula I for the manufacture of a medicament for the stimulation of the expression of endothelial NO synthase or for the treatment of various diseases including cardiovascular disorders such as atherosclerosis, thrombosis, coronary artery disease, hypertension and cardiac insufficiency, for example.

  • Sonogashira/N-acyliminium ion aromatic π-cyclisation processes: access to tetra- and pentacyclic lactams
    作者:Ronald Grigg、Visuvanathar Sridharan、David A. Sykes
    DOI:10.1016/j.tet.2008.06.044
    日期:2008.9
    Application of the Sonogashira reaction of N-alkynylimides with 2-iodophenol or 2-iodo-N-tosylaniline affords 2-(N-alkylimino)-benzofurans and indoles in good yield. Selective partial reduction of the latter followed by treatment with TsOH generates N-acyliminium ions, which cyclise to afford tetra- and pentacyclic lactams in good yield. The latter are reduced to the analogous cyclic amines by BH3. (C) 2008 Elsevier Ltd. All rights reserved.
