Synthesis and Biological Activity of Acylthiourea Derivatives Contain 1,2,3-thiadiazole and 1,3,4-thiadiazole

摘要

In order to investigate the biological activity of novel thiourea compounds, some novel 1,2,3-thiadiazole derivatives containing 1,3,4-thiadiazole were synthesized under phase transfer catalyzed condition (PEG-600) by multi-step reactions. The chemical structures of all compounds were established by H-1 NMR, FTIR, MS, and elemental analysis, and some of these compounds were investigated for fungicidal activity and plant growth regulatory activity. The bioassay results indicated that some of these compound exhibited moderate activities.
