中文摘要:以乙酰丙酮、溴乙酸乙酯和2,6-二氯吡啶为起始原料,经取代、肼基化、环合、水解、酸化及缩合等反应,得到9个未见文献报道的吡啶联吡唑乙酰基类化合物B1~B9。其结构均经核磁共振氢谱和质谱表征。初步生物活性测定表明:在150 g/hm2的处理剂量下,大部分目标化合物表现出一定的除草活性,其中化合物B2、B3、B6B8对苘麻Abutilon theophrasti Medicus、反枝苋Amaranthus retroflexus和凹头苋Amaranthus lividus L.生长的抑制率接近100%。

Synthesis and herbicidal activity of substituted 2-(1-(3-chloropyridin-2-yl)-3,5-dimethyl-1H-pyrazol-4-yl) acetic acid derivatives containing 1, 3, 4-thiadiazole
Abstract:Nine novel 2-(1-(3-chloro pyridin-2-yl)-3,5-dimethyl-1H-pyrazol-4-yl) acetic acid derivatives B1-B9 were synthesized from acetylacetone, ethyl bromoacetate and 2,6-dichloropyridine. The synthesis route included a series of reactions such as substitution, alkylation, cyclization, hydrolysis, and acidification condensation. The chemical structures were characterized by 1H NMR and MS. Preliminary bioassay showed that most of the above compounds displayed herbicidal activities at the concentration of 150 g/hm2. The inhibition rates of B2, B3, B6 and B8 against Abutilon theophrasti Medicus, Amaranthus retroflexus and Amaranthus lividus L. were nearly 100%.
