以1,5-二苯基-1,4-戊二烯-3-酮肟和酰氯为原料, 合成了15个新型的1,5-二苯基-1,4-戊二烯-3-酮肟酯类化合物, 通过元素分析, IR, 1H NMR, 13C NMR等对其结构进行了表征. 初步生物活性试验结果表明, 在50 mg•L－1浓度下, 化合物3i和3o对小麦赤霉病菌抑制率分别为51.1%和 53.4%, 与对照药剂恶霉灵抑制活性相当.

Fifteen 1,5-diphenyl-1,4-pentadien-3-one oxime esters were synthesized by the reaction of 1,5-diphenyl-1,4-pentadien-3-one oxmie with acyl chloride. Their structures were identified by elemental analysis, IR, 1H NMR and 13C NMR spectra. The preliminary bioassay showed that compounds 3i and 3o had certain antifungal activities against Fusarium graminearum with rate of 51.1% and 53.45% at a concentration of 50 mg•L－1 respectively, similarly to the control (hymexozole).

Key words: oxime ester, pentadienone, synthesis, antifungal activity
