N-Arylations of Nitrogen-Containing Heterocycles with Aryl and Heteroaryl Halides Using a Copper(I) Oxide Nanoparticle/1,10-Phenanthroline Catalytic System
and indoles, with aryl and heteroarylhalides catalyzed by copper(I) oxide (Cu 2 O) nanoparticles is demonstrated. Four types of Cu 2 O were evaluated: the bulky compound and its cubic, octahedral, and spherical nanoparticulate forms. The results show that Cu 2 O nanoparticles, in particular the cubic form, are highly efficient for the N-arylation reaction. In the presence of cubic Cu 2 O nanoparticles
演示了含氮杂环(即咪唑、三唑和吲哚)的无溶剂 N-芳基化的一般程序,其中芳基和杂芳基卤化物由氧化铜 (I) (Cu 2 O) 纳米颗粒催化。评估了四种类型的 Cu 2 O:大体积化合物及其立方、八面体和球形纳米颗粒形式。结果表明,Cu 2 O 纳米颗粒,特别是立方形式,对 N-芳基化反应非常有效。在立方 Cu 2 O 纳米粒子、1,10-菲咯啉和四丁基氟化铵存在下,多种含氮杂环在 110-145 °C 下与芳基和杂芳基卤化物顺利进行 N-芳基化反应,得到相应的产物以优异的产量。值得注意的是,该反应是在无溶剂条件下进行的。
Aqueous Micellar Medium in Organic Synthesis: Alkylations and Michael Reactions of Benzotriazole
cetyltrimethylammonium bromide in catalyzing C–N bond formation has been studied with respect to N-alkylations of benzotriazole (Bt). Alkylations with various alkylating agents and the addition of Bt across activateddoublebonds in the Michael fashion occurred successfully in fair-to-good yields in the aqueous micellar regime. These reactions provided a mixture of N-1 and N-2 alkylated products, with a marked preference

Series of benzotriazole derivatives were synthesized and evaluated for their Sodium hydrogen exchanger-1 inhibitory potential. All compounds inhibit Sodium hydrogen exchanger-1 in the in-vitro platelet swelling assay. This is perhaps the first report of NHE-1 inhibitory activity of benzotriazole. The 1-alkyl benzotriazole derivatives were found to be more active than the 2-alkyl isomers. The activity
