carbazole derivatives were synthesized for the synthesis 2,3-Dihydro-1H-carbazol-4(9H)-one O-acetyl oxime (3), ethyl 2-(2,3,4,9-tetrahydrospiro[carbazole-1,2′-[1,3]dithiolane]-2-yl)acetate (5), 2- hydroxyethyl 2,3,4,9-tetrahydrospiro[1H-carbazole-1,2′[1,3]dithiolane-4-one]-2-yl}-acetamide (7). These products (3, 5, and 7) were characterized by the spectroscopic techniques (IR, 1H NMR, 13C NMR and elemental
合成了各种咔唑衍生物,用于合成2,3-二氢-1 H-咔唑-4(9 H)-一个O-乙酰基肟(3),乙基2-(2,3,4,9-四氢螺[咔唑) -1,2'-[[1,3] dithiolane] -2-yl)acetate(5),2-羟乙基2,3,4,9-tetrahydrospiro [1 H-咔唑-1,2'[1,3 ]二硫杂环戊烷-4-酮] -2-基}-乙酰胺(7)。这些产品(3,5,和7)的特点是以光谱技术(IR,1 H NMR,131 H NMR和元素分析。然后,将观察到的研究化合物的FT-IR和NMR峰与计算值进行比较。FMO分析表明,(5)由于其较高的能隙,因此更喜欢分子间相互作用而不是分子内相互作用。NBO分析表明,n→П*和П→П*相互作用是导致稳定能降低的原因。分子对接研究表明(5)在结合位点(-7.21 kcal / mol)与人谷胱甘肽还原酶表现出最高的结合亲和力。另外,使
