The synthesis and phytotoxic activity of a series of tyrosol 1,2,3-triazole derivatives are reported herein. Target compounds were synthesized through the copper(I)-catalyzed azide-alkyne cycloaddition reaction (CuAAC), known as click reaction, and these were tested for phytotoxic activity on leaves of wild poinsettia (Euphorbia heterophylla), fleabane (Conyza sumatrensis), and tropical spiderwort
本文报道了一系列酪醇 1,2,3-三唑衍生物的合成和植物毒性活性。目标化合物是通过铜 (I) 催化的叠氮化物-炔烃环加成反应 (CuAAC) 合成的,称为点击反应,并测试了这些化合物对野生一品红 ( Euphorbia heterophylla )、羽绒 ( Conyza sumatrensis ) 和热带蜘蛛草 ( Commelina benghalensis )。这是三种高度有害的农业杂草,它们对现有的杂草控制方法提出了挑战,包括使用化学除草剂。合成并测试了 25 种化合物。没有一种化合物对C. benghalensis和C. sumatrensis显示出植物毒性活性,但几乎都在太子参叶片上产生黄变、脱色、坏死。与用作阳性对照的市售除草剂敌草快相比,两种酪醇 1,2,3-三唑衍生物产生的病变更广泛(p ≤ 0.05)。当施用于太子参叶片时,这些化合物会干扰气孔导度、净光合作用、内部碳浓度、蒸腾速率、水分利用效率以及叶绿素
