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.

Herbicidal 3-(substituted benzoxazol-7-yl) and 3-(substituted benzothiazol-7-yl)-1 -substituted-6-trifluoromethyl-2,4-(1H,3H)pyrimidinediones, compositions containing them, and methods of using them to control undesired plant growth are disclosed, as are novel intermediates used in the preparation of these compounds. The herbicidal compounds of the present invention are defined by the following generic structure: STR1 in which R is selected from a variety of substituents, including halogen, alkyl, alkenyl, alkynyl, phenyl, phenylalkyl, alkylphenylalkyl, haloalkyl, hydroxy, alkoxy, hydroxyalkyl, halophenyl, halophenylalkyl, alkoxyphenyl, sulfhydryl, alkylthio, piperidinyl, alkylamino, alkoxyalkyl, phenoxy, amino, alkylsulfonylamino, phenylsulfonylamino, and carboxy; R1 is alkyl or amino; R2 is hydrogen or halogen; X is oxygen or sulfur; Y is hydrogen, halogen, alkoxy, cyano, or nitro, and; Z is halogen; where halogen is bromine, chlorine, fluorine, or iodine, and each alkyl, alkoxy, alkenyl, or alkynyl moiety has one to six carbon atoms.
