摘要:
2-Substituted aryl sulfamonyl ureas are novel sulfonylurea compounds,in which the bridge was modified. For instance, 1-((o-cyclopropylcarbonyl)phenyl sulfamonyl)-3- (4',6'-dimeth-oxy-2-pyrimidinyl)urea is effective for the selective control of a variety of weed species in the presence of cereal crops and is especially useful for controlling broadleaf weeds and sedges[1]. For further structural study, nine aryl sulfamonyl ureas(3) were synthesized, including four 1-(o-substituted phenyl sulfamonyl)-3-(4'-substituted pyrimidin-2'-yl) ureas and five 1-(α-pyridinyl sulfamonyl)-3-(4'6'-disubstituted pyrimidin-2'-yl) ureas.
