Abstract The herbicidal activity of a set of N -methyl arylaminophenoxypropionate esters 3 has been compared to the analogous aryloxyphenoxypropionates 1. The usefulness of N -methyl as a novel bioisostere for ether links is shown by the surprisingly high herbicidal activity of the 6-chloroquinazolin-2-yl- and 7-chloro-1,2,4-benzotriazin-3-yl-N-methylamino-phenoxypropionate esters 3h and 3i.
