DBU catalyzed synthesis of fused 1,2,3-triazoles by [3+2] cycloaddition of aryl azides with activated cyclic C–H acids such as dimedone, cyclohexane-1,3-dione, 5-methylcyclohexane-1,3-dione, and 2-hydroxynaphthalene-1,4-dione in PEG-400 has been reported under heating. The important features of this reaction are high yield products, short reaction times, easy availability of starting materials, and
3k, 3l and 3m showed modest activity against CQ-sensitive strain of P. falciparum with IC50 values of 2.3 ± 0.4 μM, 2.9 ± 0.1 μM and 1.7 ± 0.06 μM, respectively. Additionally, cytotoxic properties of these derivatives against SIHA, PANC 1, MDA-MB-231, and IMR-3 cancer cell lines were also studied and the results indicated that low cytotoxic potentials of all the derivatives which indicating the high
with aromatic azides in the presence of the salophen Schiff base ligand afforded new derivatives of 1,2,3‐triazole‐based quinazoline scaffold in high‐to‐excellent reaction yields. The main advantage of this procedure is that the toxicity of the copper catalyst used could be decreased to 2 mol% by complexation with the salophen ligand. All the synthesized compounds were screened for their in vitro antibacterial
