Strobilurin derivatives have significant fungicidal activity, hence, twelve new strobilurin derivatives containing oxime ether moiety were designed and synthesized, and their structures were confirmed by 1H NMR, IR, HPLC/MS techniques and elemental analysis. Preliminary bioassay showed that most of these title compounds had potent fungicidal activity. For example, 6b～6d and 6h exhibited more than 90% ac-tivities against Blumeria graminis at a concentration of 500 μg/mL. Furthermore, compounds 6c and 6d also showed more than 90% inhibition against Pyricularia oryzae. Especially, compound 6c gave 72% control against Blumeria graminis at 25 μg/mL.

Key words: fungicidal activity, synthesis, structure-activity relationship, strobilurins
