Synthesis of Tyrosol 1,2,3-Triazole Derivatives and Their Phytotoxic Activity against .

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 (), fleabane (), and tropical spiderwort (). These are three highly noxious agricultural weeds that challenge available weed control methods, including the use of chemical herbicides.
