咪唑并[1,2- a ]吡啶衍生物已被证明具有广泛的生物活性。2-Amino-1-propargylpyridinium 和 2-amino-1-(2-bromoallyl)pyridinium bromides,其结构基于 X 射线结构分析确定,与甲醇钠反应,生成 2-甲基咪唑并[1,2- a ]吡啶。2-甲基咪唑并[1,2- a ]吡啶进一步与溴和碘反应,得到3-卤代-2-甲基-1 H-咪唑并[1,2 - a ]吡啶鎓三卤化物,其结构由X-证实射线结构分析。3-Halo-2-methyl-1 H-咪唑[1,2 - a]吡啶鎓卤化物由各自的三卤化物获得。3-Bromo-2-methyl-1 H - imidazo[1,2 - a ]pyridinium bromide在 2700 和 675 μg/ml 的浓度下显示出对金黄色葡萄球菌的抗菌特性。
A copper-catalyzed reaction of 2-amino-1-(prop-2-yn-1-yl)pyridinium bromide derivatives and aromatic sulfonylazides has been demonstrated under mild condition.
Polystyrene-supported palladium(II) ethylenediamine complex: A highly active and recyclable catalyst for the synthesis of 2-benzylimidazo[2,1-<i>b</i>]pyridines through heteroannulation of acetylenic compounds
The polymer-supported palladium(II) ethylenediamine [PS-en-Pd(II)] complex is a highly active catalyst for the heterocyclization that takes place during the Sonogashira reaction between an aryliodide and 2-amino-1-(2-propynyl)pyridinium bromide. This heterogeneous palladium catalyst can readily be recovered from the reaction medium by simple filtration and reused without a significant loss in its
bromide with various iodobenzenes, catalyzed by Pd-Cu, in the presence of sodium lauryl sulfate as the surfactant and cesium carbonate as the base, in water, leads to the formation of 2-substituted imidazo[1,2-α]pyridines.
