Gj. Bird et al., (N)UNDER-BAR-METHYL AS A BIOISOSTERE FOR THE OXYGEN LINK BETWEEN THE AROMATIC RINGS OF ARYLOXYPHENOXYPROPIONATE HERBICIDES, Bioorganic & medicinal chemistry letters, 7(12), 1997, pp. 1489-1492
The herbicidal activity of a set of (N) under bar,methyl arylaminophen
oxypropionate esters 3 has been compared to the analogous aryloxypheno
xypropionates 1. The usefulness of (N) under bar-methyl as a novel bio
isostere for ether links is shown by the surprisingly high herbicidal
activity of the 6-chloroquinazolin-2-yl- and -benzotriazin-3-yl-N-meth
ylamino-phenoxypropionate esters 3h and 3i. (C) 1997 Elsevier Science
