Synthesis and antifungal activity of novel 3,6-diaryl-5H-[1,2,4]triazolo[4, 3-b][1,2,4]triazepines

(Chemical Equation Presented) 5-Aryl-3,4-diamino-1,2,4-triazoles 5 on treatment with β-chlorocinnamaldehydes 7 in the presence of catalytic amount of p-TsOH and N,N-dimethylformamide as an energy transfer medium under microwave irradiation and as solvent with oil-bath heating at 80°C affords novel 3,6-diaryl-5H-[1,2,4]triazolo[4,3-b]-1,2,4]triazepines 8. The structures of the synthesized compounds were established on the basis of 1H NMR, IR, mass spectral data and elemental analysis.

One-pot synthesis of antifungal active 9-substituted-3-aryl-5H,13aH- quinolino [3,2-/][1,2,4]triazolo [4,3-b] [1,2,4]triazepines

The title compounds, 9-substituted-3-aryl-5H,13aH-quinolino[3,2-f][1,2,4] triazolo[4,3-b][1,2,4]triazepines 8, are synthesized from 5-aryl-3,4-diamino-1, 2,4-triazoles 5 and 2-chloro-3-formylquinolines 7 using catalytic amount of p-TsOH and N,N-dimethylformamide as an energy transfer medium using microwave heating as well as solvent using oil-bath heating at 80°C affords novel 9-substituted-3-aryl-5H,13aH-quinolino[3,2-f][1,2,4]triazolo[4,3-b][1,2,4] triazepines. The products are obtained in good to moderate yields and are in a state of high purity.
