A novel series of 7,7-diphenyl-1,2-dihydroimidazo[2,1-c][1,2,4]triazin-6(7H)-one 6a–h, were easily prepared via reactions of novel 2-hydrazinyl-4,4-diphenyl-1H-imidazol-5(4H)-one (2) with hydrazonoyl halides 3a–h. In addition, we also examined the reaction of compound 2 with commercially available active methylene compounds to afford new pyrazoles containing an imidazolone moiety, expected to be biologically active. The structures of the synthesized compounds were assigned on the basis of elemental analysis, IR, 1H-NMR and mass spectral data. The antifungal and antibacterial activities of the newly synthesized compounds were evaluated.
通过新型 2-肼基-4,4-二苯基-1H-咪唑-5(4H)-酮 (2) 与肼酰卤化物 3a-h 反应,我们很容易地制备出一系列新型 7,7-二苯基-1,2-二氢咪唑并[2,1-c][1,2,4]三嗪-6(7H)-酮 6a-h。此外,我们还研究了化合物 2 与市售的活性亚甲基化合物的反应,以获得含有咪唑酮分子的新吡唑,这些新吡唑有望具有生物活性。根据元素分析、红外光谱、1H-NMR 和质谱数据,确定了合成化合物的结构。对新合成化合物的抗真菌和抗细菌活性进行了评估。
