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 in ionic liquid as solvent under microwave heating as well as using oil-bath heating at 80 °C. The products are obtained in the good to moderate yields and in high purity. These compounds have been screened for antifungal activity. The screening data indicate that the compounds 8a, 8b, 8c and 8d show excellent activity against Aspergillus niger 1000 μg concentration and Pencillium notatum species at 500 μg as well as 1000 μg concentrations whereas, these compounds show good to moderate activity against Aspergillus flavus and Rhizopus species at both the concentrations. Moreover, ionic liquid is found to be recyclable for at least three consecutive runs what makes the process cost-effective and economic that lead to the area of Green Chemistry as recyclability is one of the most important feature of Green Chemistry.

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.
