Synthesis of Cyclopropyl Ester and Amide Substituted Pyrimidinediones as Protoporphyrinogen Oxidase-Inhibiting Herbicides

The protoporphyrinogen oxidase (PPO) enzyme is involved in the biosynthesis of chlorophyll and is an important target in research for development of new herbicides. In this study, new pyrimidinedione compounds with thioester tail group containing cyclopropyl moiety are synthesized from the commercially available 2-(1-(mercaptomethyl)cyclopropyl)acetic acid. The herbicidal activity of the synthesized compounds is also evaluated. Most of the synthesized compounds exhibit herbicidal activities against both monocot and dicot weeds. In particular, 10a showed similar activity to the control material, Saflufenacil. And when against the monocot weeds, Echinochloa crusgalli and Digitaria sanguinalis, 10a shows superior activity to Saflufenacil.

Design and synthesis of acrylate and acrylamide substituted pyrimidinediones as potential PPO herbicides

PPO herbicides emerge to be widely use in the agricultural field and a focus of research to many scientists due to its environmentally-friendly properties. In lieu with this, this study presents acrylate and acrylamide substituted pyrimidinediones as PPO herbicide candidates. Most synthesized compounds exhibits herbicidal activities against both monocot and dicot weeds, especially, compound 5a which showed non-selective superior activity against the commercialized, Saflufenacil. Compound 5a was further tested for residual effect and showed promising results as shorter period is needed to cultivate the next crops. The synthesized acrylate and acrylamide substituted pyrimidinediones, especially, 5a could potentially be utilized in the development of commercial protoporphyrinogen oxidase inhibitors with further tests and studies.
