中文摘要：

为了发现具有良好生物活性的新型先导化合物，在综合多种高活性化合物结构特点的基础上，设计合成了一系列含苯甲酰基乙烯醇结构的2．取代苯甲酰基．5-烷基-环戊酮类化合物．以己二酸二乙酯为原料，经6步反应制得目标产物，其结构经IR，^1HNMR，X射线及元素分析或高分辨质谱确证，并对该类化合物合成方法进行了探讨．初步生测结果表明，部分化合物对油菜表现出明显的抑制活性，在100μg／mL浓度下对油菜的抑制率达到60％以上．

英文摘要：

To find new lead compounds with muti-bioactivities, a series of novel 2-aroyl-5-alkylcyclopentanone derivatives containing 2-bezoylenthenol were designed on the base of various commercial products. The target compounds were synthe- sized from diethyl adipate in 6 steps. Their structures were confirmed by IR, 1H NMR spectra, X-ray and elemental analysis or HRMS. The preliminary bioassay results indicated that some compounds showed obvious inhibition effects against Brassica campestris, and the herbicidal activities were more than 60% at 100 μg/mL.
