  Ligand-Controlled α- and β-Arylation of Acyclic N-Boc Amines

  摘要：

  AbstractThe palladium‐catalyzed ligand‐controlled arylation of α‐zincated acyclic amines, obtained by directed α‐lithiation and transmetalation, is described. Whereas PtBu3 gave rise to α‐arylated Boc‐protected amines, more flexible N‐phenylazole‐based phosphine ligands induced major β‐arylation through migrative cross‐coupling.

  Design, synthesis and evaluation of peptidomimetics based on substituted bicyclic 2-pyridones—Targeting virulence of uropathogenic E. coli

  摘要：

  Substituted bicyclic 2-pyridones, termed pilicides, are dipeptide mimetics that prevent pilus assembly in uropathogenic Escherichia coli. Here, we apply rational design to produce four classes of extended peptidomimetics based on two bioactive 2-pyridones. The key intermediate in the synthesis was an amino-functionalised 2-pyridone scaffold, which could be obtained via a mild and selective nitration and subsequent reduction. Procedures were then developed to further derivatize this amino-substituted core and a total of 24 extended peptidomimetics were synthesised and evaluated for chaperone affinity and in vivo antivirulence activity in P pili producing E coli. Enhanced affinities for the target protein were observed within the generated set of compounds, while the ability to prevent pilus assembly in vivo was significantly decreased compared to the parent lead compounds. The results suggest that the limited in vivo potencies of the analogues are either uptake/distribution related or due to loss in binding specificity. (c) 2006 Elsevier Ltd. All rights reserved.

• (Tosylimino)phenyl-λ³-iodane as a Reagent for the Synthesis of Methyl Carbamates via Hofmann Rearrangement of Aromatic and Aliphatic Carboxamides
  作者：Akira Yoshimura、Matthew W. Luedtke、Viktor V. Zhdankin

  日期：2012.2.17

  A new, mild procedure for the Hofmann rearrangement of aromatic and aliphatic carboxamides using (tosylimino)phenyl-λ3-iodane, PhINTs, as a reagent is reported. Because of the mild reaction conditions, this method is particularly useful for the Hofmann rearrangement of substituted benzamides, which usually afford complex reaction mixtures with other hypervalent iodine oxidants. The mild reaction conditions

  一种新的，温和的程序使用（tosylimino）苯基-λ芳香族和脂肪族羧酰胺的霍夫曼重排3 -iodane，PhINTs，作为试剂被报告。由于反应条件温和，该方法对于取代的苯甲酰胺的霍夫曼重排特别有用，该苯甲酰胺通常会提供与其他高价碘氧化剂的复杂反应混合物。羧酰胺与PhINTs反应的温和反应条件和高选择性可以分离最初形成的不稳定异氰酸酯，或通过用醇处理将其随后转化为稳定的氨基甲酸酯。
