摘要
2-(2-羟基乙基)-1H-苯并[哒]异喹啉-1,3(2H)-二酮与2,4-二氯肉桂酰氯反应,得到了相应的肉桂酸酯类化合物3-(2,4-二氯苯基)丙烯酸-2-(1,3-二氧代-1H-苯并[哒]异喹啉-2(3H)-基)乙酯(化合物Ⅰ),其化学结构经~1H NMR和^(13)C NMR确证。室内活性实验结果表明,在质量浓度为20 mg/L时,化合物Ⅰ对小麦发芽促进率最大,达到38.8%。在质量浓度为30 mg/L时,其对小麦主根、侧根根长,茎高的促进率最大,分别为17.0%、13.0%、20.5%,优于对照药剂胺鲜酯。在质量浓度为100 mg/L时,其对小麦纹枯病菌的抑制率为93.0%。
According to active group splicing method, 2-（2-hydroxyethyl）-1H-benzo[de]isoquinoline-1,3（2H）-dione was reacted with 2,4-dichlorocinnamoyl chloride to give naphthalene diimide substituted ester compound I. The structure of the target compound was confirmed by 1H NMR and 13C NMR. The indoor rooting sprouting experiment and bactericidal activity experiment showed that at the concentration of 20 mg/L, the germination promotion rate of compound I reached 38.8%. At the concentration of 30 mg/L, the promotion rates of compound I on the main root length, lateral root length and stem height of wheat were 17.0%, 13.0%, 20.5%, respectively. At the concentration of 100 mg/L, the inhibition rate against R. cerealis reached 93.0%.
