主 题:Aryloxyphenoxy propionamide Allyloxy Propargyloxy Herbicidal activity Crop selectivity
摘 要:A series of novel N-allyloxy/propargyloxy aryloxyphenoxy propionamide compounds was designed and prepared. The structures of the synthesized compounds were confirmed by means of 1H NMR, 13C NMR, LC-MS, elemental analysis and IR. The bioassay results indicate that when against Digitaria sanguinalis and Echinochloa crus-galli, (R)-N-(propargyloxy)-2-{4-[(6-chloroquinoxalin-2-yl) oxy] phenoxy}propanamide(1m)(IC50=6.8 and 6.5 g/hm2, respectively) and (R)-N-(allyloxy)-2-{4-[(6-chloroquinoxalin-2-yl) oxy]phenoxy}propanamide(1r)(IC50=7.4 and 6.0 g/hm2, respectively) are much more effective than commercial aryloxyphenoxypropionic ester herbicide clodinafop-propargyl(IC50=46.5 and 14.6 g/hm2, respectively). The results of crop selectivity show that compounds 1m and 1r are safe to soybean, rape and cotton and can be used as herbicides for soybean, rape and cotton crop.
