摘要：
To find new higher fungicidal activities lead compounds and develop new eco-friendly agrochemicals, natural product phenazine-1-carboxylic acid (PCA) as scaffold, a series of 1,3,4-oxadiazol-2-yl thioether derivatives was synthesized and bio-assayed. The results reveal that most target compounds possessed moderate to good fungicidal activities against R. solani, S. sclerotioru and P. oryzac Cavgra. Compounds 6n and 6o exhibit more than 90% bioactivity against S. sclerotioru. The EC50 value of compounds 6n and 6o are 11.16 and 30.47 mu M respectively, in particular, compound 6n show equal activity against S. sclerotioru to PCA (10.49 mu M). This result provides a valuable lead compound for further studies. [GRAPHICS] .
