Strobilurins have become one of the most important classes of agricultural fungicides. To discover new strobilurin derivatives with high activity against resistant pathogens, a series of novel β-methoxyacrylate analogues were designed and synthesized by integrating substituted pyrimidine with a strobilurin pharmacophore. The compounds were confirmed and characterized by infrared, 1H nuclear magnetic resonance, elemental analysis and mass spectroscopy. The bioassays indicated that most of the compounds 1 exhibited potent antifungal activity against Colletotrichum orbiculare, Botrytis cinerea Pers and Phytophthora capsici Leonian at the concentration of 50 μg/mL. Exhilaratingly, compound 1a (R=methyl) showed better antifungal activity against all the tested fungi than the commercial strobilurin fungicide azoxystrobin. Copyright

, (2008/06/13)
Phenylpyrimidines of the formula I as defined below are suitable as antidotes for protecting cultivated plants from phytotoxic effects caused by herbicides. These antidotes, either together with the herbicides or also by themselves, are applied to the pla
