A novel, efficient and mild KHSO4 mediatedsynthesis for 2-amino-1,3,4-oxadiazoles has been established via the cyclodesulfurization of benzoylhydrazine and isothiocyanate derivatives in one pot. The reactions proceeded smoothly at room temperature and produced corresponding products in moderate to good yields. This protocol also showed good functional group tolerance.
an orthorhombic system with space group P b c n. The fingerprint plots associated with Hirshfeld surface analysis indicate that there are different types of weakinteractions viz. C-H···N, O-H···N and C-H···O. The DFT calculations are also performed to verify physiochemical properties of Hppo and the results obtained are in good agreement with the experimental results. The HOMO and LUMO energy gap of
新型合成分子的合成和筛选作为治疗癌症的潜在治疗剂受到关注。在本研究中,合成了一种新化合物 5(4-羟基苯基)-2-(N-苯基氨基)-1,3,4-恶二唑 (Hppo),并研究了其对道尔顿淋巴瘤 (DL) 肿瘤细胞的抗癌活性来源于鼠 T 细胞淋巴瘤。Hppo 已通过 IR、NMR 和单晶 X 射线数据进行表征。Hppo 的结构通过氢键相互作用而稳定,并在空间群为 P bc n 的正交系统中结晶。与 Hirshfeld 表面分析相关的指纹图表明存在不同类型的弱相互作用,即。CH…N、OH…N 和 CH…O。还进行了 DFT 计算以验证 Hppo 的理化性质, 获得的结果与实验结果非常吻合。Hppo 的 7.344 eV 的 HOMO 和 LUMO 能隙表明良好的 NLO 特性。使用 MTT 法测试了 Hppo 对道尔顿淋巴瘤细胞的细胞毒性活性,结果表明该化合物显示出令人钦佩的抗癌活性 (IC 50=
