Several 3-alkylphenols including 3-undecylphenol, which was isolated from a Sumatran rainforest plant, were synthesized to investigate their antinematodal activity against the phytopathogenic nematodes, Bursapherencus xylophilus. A three-step synthesis involving the treatment of 2-cyclohexen-1-one with the Grignard reagent, oxidation of the resulting 1-alkyl-2-cyclohexen-1-ol and subsequent aromatization of 3-alkyl-2-cyclohexen-1-one successfully afforded such phenols. Among the 3-alkylphenols, 3-nonylphenol showed the highest activity, while 3-decylphenol and 3-undecylphenol also showed high activity.
合成了几种3-烷基苯酚,包括从苏门答腊雨林植物中分离出的3-十一烷基苯酚,以研究它们对植物病原线虫Bursaphelenchus xylophilus的抗线虫活性。该合成过程经过三个步骤,包括将2-环己烯-1-酮与格氏试剂反应、氧化所得的1-烷基-2-环己烯-1-醇,以及随后对3-烷基-2-环己烯-1-酮的芳构化,成功地制备了这些苯酚。在这些3-烷基苯酚中,3-癸基苯酚显示出最高活性,而3-癸基苯酚和3-十一烷基苯酚也表现出较高的活性。
