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.

The present invention relates to a process for the preparation of montelukast sodium salt. The process includes (a) reacting 2-(2-(3-(S)-(3-(7-chloro-2- quinolinyl)-ethenyl) phenyl)-3-hydroxypropyl)- phenyl-2-propanol of Formula (II) with diphenyl chloro phosphate to get a compound of Formula III; (b) condensing the compound of Formula III with a compound of Formula IV to get compound of Formula V; (c) and converting the compound of Formula V to montelukast sodium of Formula (I).
