【摘要】 通过2-氨基噻二唑与芳氧乙酰基异氰酸酯反应合成了11种新的N-(1,3,4-噻二唑-2-基)-N′-芳氧乙酰基脲化合物,产率为50.2%~68.7%。用红外光谱、核磁共振氢谱和元素分析测试技术确证了它们的结构,初步的生物活性测试实验表明,部分目标化合物具有优良的植物生长调节活性,其中2d、2e和2k生长素活性的促进率分别达到40.1%、35.5%和28.8%。更多还原

【Abstract】 Eleven new aryloxyacetyl ureas were synthesized by the reaction of 2-amino-1,3,4-thiodiazole with aryloxyacetyl isocynates in yields of 50.2%~68.7%. Their structures were confirmed by IR, 1H NMR and elemental analysis. The preliminary biological activity tests show that some target compounds have good activities as plant growth regulator. Compounds 2d, 2e, 2k have a relatively good activity of auxin and the promoting rates of them are 40.1%, 35.5% and 28.8% respectively.更多还原
