芳脲基酰基硫脲衍生物的固相研磨合成及其植物生长活性

在无溶剂条件下，室温研磨合成了11个未见报道的芳脲基酰基硫脲类化合物，经核磁共振氢谱、红外光谱和元素分析确定结构，并进行了初步的生物活性试验，结果表明，浓度采用10 mg/L时，一些目标化合物具有较好的植物生长调节活性，其中N-苯脲基-N′-肉桂酰基硫脲和N-对甲苯脲基-N′-肉桂酰基硫脲具有较好的生长素活性，分别为54.13%和46.79%；N-对甲苯脲基-N′-肉桂酰基硫脲和N-对甲苯脲基-N′-苯氧乙酰基硫脲具有较好的细胞分裂素活性，分别为55.11%和51.14%。

Solid Phase Grinding Synthesis and Plant Growth Activities of Arylureido-acylthiourea Derivatives

Eleven new arylureido-acylthiourea derivatives have been synthesized by solid phase grinding under solvent-free conditions at room temperature. Their structures were confirmed by 1H NMR, IR and elementary analysis. The results of biological activity tests show that some target compounds have evident activity on plant growth when the concentration is 10 mg/L. Among these, N-phenylureido-N′-cinnamic acylthiourea and N-p-methylphenylureido N′-cinnamic acylthiourea have good auxins activity, the effects are 54.13% and 46.79%, respectively, while N-p-methylphenylureido-N′-cinnamic acylthiourea and N-p-methylphenylureido-N′-phenoxyacetyl thiourea have excellent activity of cytokinin, the effects are 55.11% and 51.14%, respectively.
