The research resulted in the production of new tetrazoline derivatives. Firstly; the reaction of N-acetyl chloro cyclic imides with hydrazine hydrate to give compounds (1,2). Then, compounds (1,2) were reacted with different aromatic aldehydes to give Schiff bases (3-10). The compounds of N-( 2-chloro acetyl) cyclic imides were reacted with sodium azide to give N-(azido acetyl) cyclic imides (11,12). Finally, the reaction of the prepared Schiff bases compounds with azide compounds and cyclization to gave 5-aryl tetrazoline on cyclic imides (13-20). The prepared compounds were characterized by Fourier transform infrared spectroscopy (FT-IR) and some of them byProton nuclear magnetic resonance (1H-NMR), melting point, and were studied the effects of the preparing compounds on some strains of bacteria and fungi.
这项研究产生了新的四唑啉衍生物。首先,N-乙酰基氯环酰亚胺与水合肼反应生成化合物(1,2)。然后,化合物(1,2)与不同的芳香醛反应,得到希夫碱(3-10)。N-( 2-氯乙酰基) 环酰亚胺化合物与叠氮化钠反应,得到 N-(叠氮乙酰基) 环酰亚胺 (11,12)。最后,将制备的希夫碱化合物与叠氮化合物反应并环化,得到环状亚胺上的 5-芳基四唑啉(13-20)。利用傅立叶变换红外光谱(FT-IR)对制备的化合物进行了表征,并利用质子核磁共振(1H-NMR)和熔点对其中一些化合物进行了表征,还研究了制备的化合物对一些细菌和真菌菌株的影响。
