  Benzylamines: synthesis and evaluation of antimycobacterial properties

  摘要：

  The synthesis of benzylamines with various N-alkyl chains and substituents in the aromatic system as well as their evaluation on Mycobacterium tuberculosis H 37 Ra are described. The most active compounds in this test, N-methyl-3-chlorobenzylamine (19, MIC 10.2 micrograms/mL), N-methyl-3,5-dichlorobenzylamine (93, MIC 10.2 micrograms/mL), and N-butyl-3,5-difluorobenzylamine (103, MIC 6.4 micrograms/mL), also exhibited a marked inhibitory effect on Mycobacterium marinum and Mycobacterium lufu used for the determination of antileprotic properties. The combinations of 93 with aminosalicylic acid, streptomycin, or dapsone exert marked supra-additive effects on M. tuberculosis H 37 Ra.

  By sequencing the Van Leusen imidazole and oxazole syntheses with Suzuki, Heck and Sonogashira reactions, diverse libraries of C5‐functionalized imidazoles and oxazoles were synthesized in one‐pot reactions employing [BMIM][X] as a solvent and [PAIM][NTf2] as a base.

• A Latent Reaction in a Model GFP Chromophore Revealed upon Confinement: Photohydroxylation of <i>ortho</i>-Halo Benzylidene-3-methylimidazolidiones via an Electrocylization Process

  Excited state behavior of halogen substituted model GFP chromophores was investigated in an acetonitrile solution and in a confined environment provided by an octa acid capsule in water. Of the ortho, meta, and para halogen substituted GFP chromophores only the ortho compounds gave a new product resulting from an unprecedented photosubstitution of halogens by the hydroxyl group. This unusual reaction

  在乙腈溶液中以及在辛酸胶囊在水中提供的密闭环境中，研究了卤素取代的GFP型发色团的激发态行为。在邻位，间位和对位卤素取代的GFP生色团中，仅邻位化合物会产生新产物，这是由于卤素通过羟基空前的光解而产生的。这种不寻常的反应凸显了密闭空间在实现某些无法实现的光反应中的重要性。
• Multicomponent Synthesis of Substituted and Fused-Ring Imidazoles via Phospha-münchnone Cycloaddition

  A new, one-pot synthesis of imidazoles from imines, acid chlorides, and N-nosyl imines or tethered nitriles is reported. The reaction is mediated by the phosphonite PPh(catechyl) and proceeds via regioselective cycloaddition with an in situ-generated phospha-münchnone 1,3-dipole. This provides an efficient route to construct both highly substituted and polycyclic imidazoles directly from available

• Steric and Electronic Effects in Capsule-Confined Green Fluorescent Protein Chromophores
  作者：Anthony Baldridge、Shampa R. Samanta、Nithyanandhan Jayaraj、V. Ramamurthy、Laren M. Tolbert

  DOI：10.1021/ja1094606

  日期：2011.2.2

  The turn-on of emission in fluorescent protein chromophores sequestered in an "octaacid" capsule is controlled by stereoelectronic effects described by a linear free energy relationship. The stereochemical effects are governed by both the positions and volumes of the aryl substituents, while the electronic effects, including ortho effects, can be treated with Hammett sigma parameters. The use of substituent volumes rather than A values reflects packing of the molecule within the confines of the capsule.
