    Electrochemical-induced transfer hydrogenation (TH) of N-heteroaromatic to construct biologically active functional molecule is an appealing and yet challenging task. We report herein the first selective transfer hydrogenation of imidazopyridine derivatives with secondary amines as the hydrogen donors under electrochemical conditions.

  • Substituent Effects on Fluorescent Properties of Imidazo[1,2-<b><i>a</i></b>]pyridine-Based Compounds

    日期:1999.6
    In order to search for novel fluorescent organic compounds, 20 derivatives of imidazo[1,2-a]pyridine (1) were synthesized, and their fluorescent properties were studied. Though the parent compound 1 (λfl = 370.5 nm, Φ = 0.57 in ethanol) was in the liquid state at ambient temperature, 2-phenylimidazo[1,2-a]pyridine (5), 2-(2-naphthyl)imidazo[1,2-a]pyridine (16), 7-methylimidazo[1,2-a]pyridine (3), 7-methyl-2-phenylimidazo[1,2-a]pyridine (12), and 7-methyl-2-(2-naphthyl)imidazo[1,2-a]pyridine (17) were found to give thermally stable solid compounds (mp 55—190 °C) without much affecting the fluorescent properties of the parent compound (λfl = 374—381 nm, Φ = 0.50—0.78 in ethanol). Among the 4′-substituted 2-phenyl derivatives, it was found that the introduction of the strong electron-donating amino and dimethylamino groups (2-(4-aminophenyl)imidazo[1,2-a]pyridine (7) and 2-[4-(dimethylamino)phenyl]imidazo[1,2-a]pyridine (8), respectively) caused marked red shift of their fluorescence (λfl = 445 and 446 nm, respectively, in ethanol), thus providing the way for tuning the fluorescence color of the IP derivatives. The observed red shift of the fluorescence of 7 and 8 was ascribed to the contribution of the excited intramolecular charge transfer state.
    为了寻找新型荧光有机化合物,合成了20种咪唑并[1,2-a]吡啶(1)的衍生物,并研究了它们的荧光性质。尽管母体化合物1在室温下为液态(λfl = 370.5 nm,Φ = 0.57,在乙醇中),但2-苯基咪唑并[1,2-a]吡啶(5)、2-(2-萘基)咪唑并[1,2-a]吡啶(16)、7-甲基咪唑并[1,2-a]吡啶(3)、7-甲基-2-苯基咪唑并[1,2-a]吡啶(12)和7-甲基-2-(2-萘基)咪唑并[1,2-a]吡啶(17)被发现能形成热稳定的固态化合物(熔点55-190°C),且对母体化合物的荧光性质影响不大(λfl = 374-381 nm,Φ = 0.50-0.78,在乙醇中)。在4'-取代的2-苯基衍生物中,发现引入强电子供体的氨基和二甲氨基(分别为2-(4-氨基苯基)咪唑并[1,2-a]吡啶(7)和2-[4-(二甲氨基)苯基]咪唑并[1,2-a]吡啶(8))会导致它们的荧光显著红移(λfl = 445和446 nm,在乙醇中),从而提供了调节IP衍生物荧光颜色的途径。7和8荧光的红移归因于激发态分子内电荷转移态的贡献。

    The electrochemical-induced regioselective C-3 thiomethylation of imidazopyridines has been initially accomplished via a three-component cross-coupling strategy using thiocyanate as the sulfur source and methanol as the methyl reagent. This protocol provides a green method for the thiomethylation of imidazopyridines without the need for any exogenous oxidants and metal catalysts under room temperature
    咪唑并吡啶类化合物的电化学诱导的区域选择性C-3硫代甲基化反应最初是通过三组分交叉偶联策略完成的,使用硫氰酸盐作为硫源,甲醇作为甲基试剂。该方案为咪唑并吡啶的硫代甲基化提供了一种绿色方法,在室温条件下无需任何外来氧化剂和金属催化剂。宽泛的官能团可以耐受,从而以高收率生产区域选择性的C-3硫代甲基化产品。重要的是,这种电化学氧化诱导的硫代甲基化反应可以容易地以优异的效率放大。

    A direct and efficient protocol for thiocyanation of imidazoheterocycles accompanying with the hydrogen evolution under electrochemical oxidation has been described. Various important thiocyanated and selenocyanated imidazoheterocycles have been constructed through this method in moderate to excellent yields and can easily be scaled up. Further mechanistic studies suggest that aryl radical cation is

    hassle free sustainable protocol for the sulfenylation of imidazoheterocycles has been developed. Sulfonyl hydrazides have been used as the generator of active thio carrier in situ in the form of “sulfono thionate” under neat condition to produce the desired sulfenylated imidazoheterocycles in good to excellent yields. The new methodology does not demand the requirement of any solvent or catalyst by simply
