A novel method for the preparation of 4-aryl-1H-1,2,3-triazoles (I) (aryl = R = Ph, 4-MeC6H4, 4-Cl-3-F3CC6H3, 4-morpholinyl-3-F3CC6H3, 4-piperidinyl-3-F3CC6H3, etc.) from arylglyoxaldoxime semicarbazones HON:CHCR:NNHC(O)NH2 with sodium dithionite and O2 was developed and found to be safer than the Huisgen azide-alkyne dipolar cycloaddition A total of 17 new 4-aryl-1H-1,2,3-triazoles were prepared and characterized by 1H NMR, 13C NMR and ESI-MS. Subsequently, their in-vitro antihepatoma activities were evaluated on human hepatoma QGY-7703, Bel-7402 and SMMC-7721 cell lines and mouse fibroblast cells L-929 by MTS assay. Among them, I (R = 4-Cl-3-F3CC6H3) exhibited excellent activity against QGY-7703 (GI50 = 0.0232 μM), while I (R = 4-morpholinyl-3-F3CC6H3, 4-piperidinyl-3-F3CC6H3) displayed good activity (GI50 = 0.103 μM and GI50 = 0.182 μM, resp.) against the growth of SMMC-7721 cell lines. Furthermore, these three triazoles showed slight selectivity of inhibition of hepatoma cell lines over normal cell line L-929. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Recommanded Product: 4-(p-Tolyl)-1H-1,2,3-triazole

On May 31, 2010, Coelho, Alberto; Diz, Paula; Caamano, Olga; Sotelo, Eddy published an article.Category: triazoles The title of the article was Polymer-Supported 1,5,7-Triazabicyclo[4.4.0]dec-5-ene as Polyvalent Ligands in the Copper-Catalyzed Huisgen 1,3-Dipolar Cycloaddition. And the article contained the following:

New supported catalysts for the Huisgen’s [3+2] azide-alkyne cycloaddition have been prepared by immobilization of copper species on com. available polymeric matrixes incorporating the 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) template. The synergic exploitation of the exceptional copper chelating ability and basicity profile of the TBD framework, in addition to ensuring effective immobilization and stabilization of copper species, allows the implementation of three-component strategies. The new catalytic systems enabled the development of regioselective, efficient, modular, mild and eco-friendly multicomponent syntheses of diversely decorated 1,2,3-triazoles, contributing to expand the scope and versatility of the Cu-catalyzed Huisgen 1,3-dipolar cycloaddition The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Category: triazoles

Aza-Michael addition of 4-aryl-1H-1,2,3-triazoles to 2-cycloalken-1-ones was studied in the presence of DABCO as organic base. The reactions were carried out in acetonitrile at room temperature to provide 2,4-disubstituted 2H-1,2,3-triazoles I [R = H, Me; Ar = C6H5, 4-MeC6H4, 2-MeO-1-naphthyl, etc.; n = 1] as major adducts and 1,4-disubstituted 1H-1,2,3-triazoles II [n = 0] as minor adducts. Though the reaction times are longer (4-8 days), the two regioisomers were separated by using column chromatog. and the adducts were obtained in very good to excellent combined chem. yields. The electron-rich and electron-poor substituents on aryl moiety of 4-aryl-triazoles could tolerate the reaction conditions to afford the title adducts.
