以去氢枞酸为原料,制备去氢枞酸酰氯.以脂肪族二酸为原料,经过脂肪族二酸二乙酯得到脂肪族二酸二酰肼.脂肪族二酸二酰肼与去氢枞酸酰氯在相转移催化下反应得到N,N’-二去氢枞酰基取代脂肪族二酸二酰肼,再脱水环合,得到5个标题化合物脂肪族二酸二烷基双去氢枞基双噁二唑.通过元素分析,IR,MS,1H NMR和13C NMR对所合成的新化合物进行了结构表征.初步的除草活性测试表明,化合物6b～6e在100μg/mL浓度下对油菜的胚根生长具有良好的抑制作用,抑制率均超过80%.
Dehydroabietic acid is prepared from dehydroabietic acid as dehydroabietic acid chloride, and aliphatic diacid is taken as raw material to obtain aliphatic diacid hydrazide through aliphatic diacid ... ... aliphatic diacid hydrazide and dehydrogenation The abietic acid chloride is reacted under phase transfer catalysis to obtain N, N’-didehydroabietyl substituted aliphatic diacid dihydrazide, which is then dehydrated and cyclized to obtain 5 of the title compounds. Aliphatic diacid dialkyl dehydrogenase The structure of the new compounds were characterized by elemental analysis, IR, MS, 1H NMR and 13C NMR.The preliminary herbicidal activity tests showed that the compounds 6b ~ 6e exhibited the highest activity against rapeseed at 100μg / mL Radicle growth has a good inhibitory effect, inhibition rates were more than 80%.
