Abstract
Aryloxyphenoxypropionates (APPs) are a class of herbicides targeting on acetyl-coenzyme A carboxylase (AC-Case) in monocot chloroplast. The article presents synthesis of twenty three novel ethyl 2-(4-(pyridin-2-yl-oxy)phenylamino)-propanoates/acetates, and their structures were characterized by 1 H NMR, HRMS and X-ray single-crystal diffraction. The herbicidal activities on barnyard grass and rape of the novel compounds were evaluated. Ethyl 2-(4-(5-nitropyridin-2-yloxy)-phenylamino)propanoate ( B5 ) showed almost the same level of herbicidal activity on barnyard grass as commercial herbicide fluazifop-methyl which could become a potential lead compound on weeds.
