Synthesis,Crystal Structure,and Biological Activity of Naphthalen-2-yl4-methyl-1,2,3-thiadiazole-5-carboxylate被引量:2
2011年
The title compound naphthalen-2-yl-4-methyl-1,2,3-thiadiazole-5-carboxylate (C 14 H 10 N 2 O 2 S,M r=270.31) was synthesized by the reaction of 4-methyl-1,2,3-thiadiazole-5-carbonyl chloride with 2-naphthol,and its structure was characterized by IR,1 H NMR,high-resolution mass spectrometry and single-crystal X-ray diffraction.The crystal belongs to orthorhombic,space group Pbcn with a=23.475(5),b=9.6640(19),c=10.814(2),β=90.00°,Z=8,V=2453.2(9) 3,M r=270.30,D c=1.464 g/cm 3,μ=0.262 mm-1,F(000)=1120,R=0.0444 and wR=0.1099.X-ray analysis revealed that the thiadiazole and naphthalene rings were non-planar,while the thiadiazole ring and the ester group were essentially planar,and two intermolecular hydrogen bonds C(6) H(6)···O(1) and C(14) H(14)···O(1) were observed.The preliminary biological test showed that the title compound had antifungal and antivirus activities against tobacco mosaic virus.

Synthesis,Crystal Structure and Biological Activity of N-tert-butyl-N-(4-methyl-1,2,3-thiadiazole)-5-yl-N’-(4-methyl-1,2,3-thiadiazole)-5-formyl-N’-3,5-dichloropyridin-2-yl-diacylhydrazine被引量:2
2011年
The title compound N-tert-butyl-N-(4-methyl-1,2,3-thiadiazole)-5-yl-N'-(4-me-thyl-1,2,3-thiadiazole)-5-formyl-N'-3,5-dichloropyrid-2-yl-diacylhydrazines (C18H17Cl2N7O3S2, Mr = 514.41) has been synthesized by the reaction of N-tert-butyl-N'-3,6-dichloropyridine-2-formyl hydrazine with 4-methyl-1,2,3-thiadiazole-5-carbonyl chloride and triethylamine, and its structure was characterized by 1H NMR, HR MS, and single-crystal X-ray diffraction. The crystal of the title compound belongs to monoclinic, space group C2/c with a = 27.726(8), b = 11.045(3), c = 14.507(4)A, β = 96.758(4)°, Z = 8, V = 4412(2) A^3, Dc = 1.549 g/cm^3, μ = 0.521 mm^-1, F(000) = 2112, R = 0.0405 and wR = 0.1153. X-ray analysis indicates that all rings are non-planar in this molecule. The bioassay results indicate that both the title compound and the positive control RH-5992 have weak fungicide activities, while the title compound has good insecticidal activity against Plutella xylostella L. and no insecticidal activity against Culex pipiens pallens.

Ugi反应合成4-甲基-1,2,3-噻二唑化合物及其抗烟草花叶病毒活性(英文)被引量:2
2010年
为了寻找更多高活性化合物和进行先导结构的衍生,利用Ugi反应设计合成了18个4-甲基-1,2,3-噻二唑新化合物(I-1~I-18),其结构均经核磁共振氢谱、红外光谱和高分辨质谱的表征和确认。杀菌、抗病毒以及诱导活性的筛选结果表明:目标化合物I-3和I-11抗烟草花叶病毒(TMV)的半叶法活性高于对照药剂病毒唑,I-6的保护活性和钝化活性高于病毒唑,I-12的治疗活性高于病毒唑,I-16的诱导活性高于对照药剂噻酰菌胺;氟原子的引入有利于保持和提高新化合物的抗病毒活性,4-甲基-1,2,3-噻二唑和氟原子是新化合物抗病毒的重要活性亚结构单元。Ugi反应是新农药创制中先导优化的绿色手段。
