摘要:

将羟基香茅醛(1)与盐酸羟胺反应合成羟基香茅醛肟(2),再与溴代烷反应制得4种羟基香茅醛肟烷基醚(3a~3d),用GC-MS、IR和NMR对产物结构进行了表征。采用平皿法测定了羟基香茅醛肟及其烷基醚在不同浓度下对一年生黑麦草生长的抑制作用,结果表明:化合物3b(0.31 mmol/L)、化合物3c(0.63 mmol/L)、化合物3d(2.50 mmol/L)对一年生黑麦草根的生长抑制率高于阳性对照敌草隆(10 mmol/L)对黑麦草根的抑制率(94.1%);化合物3b(0.31 mmol/L)、3d(0.31 mmol/L),化合物3c(0.63 mmol/L)对一年生黑麦草茎的生长抑制率高于敌草隆(10 mmol/L)对黑麦草茎的抑制率(88.10%)。

Abstract:

Hydroxycitronellal oxime(2) was synthesized from hydroxycitronellal(1) and hydroxylammonium chloride, and then reacted with bromoalkanes to give 4 hydroxycitronellal oxime alkyl ethers(3a-3d). The structures of the products were characterized by GC-MS, IR and NMR.The inhibitory effect of oxime and its alkyl ethers on the growth of annual ryegrass in different concentrations were determined by the plate method. The results showed that when the concentration of 3b was 0.31 mmol/L, the concentration of 3c was 0.63 mmol/L and the concentration of 3d was 2.50 mmol/L, the growth inhibition rate of the annual ryegrass roots were higher than that of diuronat the concentration of 10 mmol/L(94.1%). When the concentration of 3b and 3d were 0.31 mmol/L and the concentration of 3c was 0.63 mmol/L, the inhibitory rate on the growth of annual ryegrass stemswere higher than that of diuron at the concentration of 10 mmol/L(88.10%).
