摘要:The present invention holds forth improvements in the field of herbicide synthesis, their application, and methods of plant and weed control and antifouling. The present invention includes the synthesis of new acrylate and methacrylate derivatives of a glyphosate. Two isomers resulting from a hindered rotation around the amide CN bond are observed for both acrylic and methacrylic analogs and barriers for internal rotation are obtained. Biological activity tests indicate that functionalized glyphosates possess herbicidal activity similar to the parent compound.
