In order to find triazole lead compounds with fungicidal activity, a series of new triazole derivatives containing coumarin ring and thioether structure were synthesized by the introduction of coumarin ring and thioether structural unit into molecules of triazoles. They were structurally confirmed by ¹H NMR, ¹³C NMR, IR, MS and elemental analysis. The preliminary bioactivity test showed that some of the target compounds have certain fungicidal activity at the test concentration.
