In order to find novel leading structures of pesticide, a series of N-（pyrimidin-5-yl）-N1-phenylureas （4a-4h） were designed and synthesized from 4-chloro-2-diethylamino-6-methyl-5-nitropyrimidine 1 via substitutio...In order to find novel leading structures of pesticide, a series of N-（pyrimidin-5-yl）-N1-phenylureas （4a-4h） were designed and synthesized from 4-chloro-2-diethylamino-6-methyl-5-nitropyrimidine 1 via substitution, reduction and acylation procedures. Preliminary bioassay showed that all the target compounds processing good anti-TMV （tobacco mosaic virus） activity. Two compounds （4d and 4e） displayed higher activity superior to virazole at a concentration of 5.0 ×10^-4 g/mE.展开更多
