Abstract:
A novel series of 3-arylbenzylidene-1H-benzo[4,5] imidazo[2,1-c][1,4]oxazine-1,4(3H)-dione (4a-l) was synthesized in moderate to good yields. The structures of the newly synthesized compounds were confirmed by 1H NMR, 13C NMR mass spectrometry and elemental analysis. The synthesized compounds were evaluated for their anti-bacterial and anti-oxidant activities. Among all the derivatives tested, the compound 3-(3,5- dimethoxy benzylidene)-1H-benzo [4,5]imidazo[2,1- c][1,4]oxazine-1,4-(3H)-dione showed more potent activity and 3-(4-methoxybenzylidene)-1H benzo[4,5] imidazo[2,1-c][1,4]oxazine-1,4(

Abstract:
The appropriate 1-arylhydrazinecarbonitriles 1a–c are subjected to the reaction with 2-chloro-4,5-dihydro-1H-imidazole (2), yielding 7-(4,5-dihydro-1H-imidazol-2-yl)-2-aryl-6,7-dihydro-2H-imidazo[2,1-c][1,2,4]triazol-3(5H)-imines 3a–c, which are subsequently converted into the corresponding amides 4a–e, 8a–c, sulfonamides 5a–n, 9, ureas 6a–I, and thioureas 7a–d. The structures of the newly prepared derivatives 3a–c, 4a–e, 5a–n, 6a–i, 7a–d, 8a–c, and 9 are confirmed by IR, NMR spectroscopic data, as well as single-crystal X-ray analyses of 5e and 8c.

Abstract:
A practical synthetic route to an important pharmaceutical intermediate 1-methyl-4-phenyl-1H-imidazol-2-amine, via a three-step sequence involving cyclisation, hydrolysis and methylation, is reported. In the process of optimisation, a novel chemical entity was isolated and confirmed to be 2,6-diphenyl-1H-imidazo[1,2-a]imidazole by MS, 1H NMR and 13C NMR. The scale-up experiment was carried out to provide 1-methyl-4-phenyl-1H-imidazol-2-amine in 27.4% total yield.

Abstract:
New molecules with promising insecticidal properties like imidazo[2,1-c][124] triazole analogs were synthesized, starting with imidacloprid and bio-assayed. The structures of synthesized molecules were confirmed with diverse modern methods like FT-IR, 1H NMR, 13C NMR, and Mass spectrometry. The synthesized molecules are screened to investigate their insecticidal and anti-bacterial activity. The bioassay screening showed that synthesized compounds chloro (3-(4-chlorophenyl)-7-[(6-chloropyridin-3-yl)methyl]-2,5,6,7-tetrahydro-3H-imidazo [2,1-c] [1,2,4] triazole (4b), the 3-(2-chlorophenyl)-7-[(6
