N-萘乙酰基-N′-对氯苯甲酰氨基硫脲的合成及其生物活性研究

通过α-萘乙酸和SOCl2在无水苯中反应制得α-萘乙酰氯,然后与硫氰酸钾反应生成α-萘乙酰基异硫氰酸酯,再与对氯苯甲酰肼进行加成反应,合成了新型化合物N-萘乙酰基-N′-对氯苯甲酰氨基硫脲,用薄层色谱法跟踪最后一步反应,确定了反应时间。产物经1HNMRI、R和元素分析进行表征。生物活性实验结果表明,其对稻子根生长具有促进作用,对大肠杆菌和枯草杆菌无明显抑菌作用。

Crystal Structure of Diethyl 1-(p-toluenesulfonamido)-p-chlorophenylmethylphosphonate

The crystal and molecular structure of diethyl l-(p-toluenesulfon-amido ) - p chlofoPhenylmet hylphosphonate has been determined by X- ray d iffractionmethod- The crystal (C18,H23,ClNO5PS) is monoclinic with space group P21/c, a =8. 162(6), b= l8. O64(7), c= l4. 362(4) A, β=96. 29(3)°, V=2lO4. 7 A3, M.=431, 88, Z=4, Dx= l. 364 g/cm3, μ, = 3. 765 cm-1, F(000) = 904, R=0. 047 andRw=0. 0049 for 998 reflections with I>3σ(I). The 1H NMR spetrum of the title com-pound shows that the two ethoxy groups are magnetic nonequivalent, which is in agree-ment with its X-ray analysis result-
