Zhang, Hao published the artcileDesign, Synthesis and Herbicidal Activities of Tetrahydroisoindoline-1,3-dione Derivatives Containing Alkoxycarbonyl Substituted 2-Benzoxazolinone, Application of Ethyl 2-Iodopropionate, the publication is Chinese Journal of Chemistry (2015), 33(7), 749-755, database is CAplus.
Several different alkoxycarbonyl-substituted 2-benzoxazolinone moieties were incorporated into a tetrahydroisoindoline-1,3-dione scaffold to provide 25 compounds (1,3-dioxo-4,5,6,7-tetrahydroisoindol-2(3H)-yl)-6-halo-alkoxycarbonyl benzoxazolinones e.g., I. The structures of these compounds were confirmed by 1H and 13C NMR, HRMS and X-ray single-crystal diffraction. Some of these compounds I [R = Me propanoate, Et propanoate, ethyl-2-butanoate, ethyl-4-butanoate] exhibited excellent herbicidal activities against Abutilon theophrasti, Amaranthus retroflexus and Echinochloa crus-galli at a rate of 375 g AI·ha-1. Among them, compounds I [R = Et propanoate, ethyl-2-butanoate] displayed the best post-emergence herbicidal effect against Abutilon theophrasti with ED50 values of 1.8 and 5.3 g AI·ha-1, resp., which are superior to that of the com. acifluorfen (44.3 g AI·ha-1). Field trials demonstrated that compound I [R = Et propanoate] exhibited similar herbicidal activity to a high concentration atrazine, and found to be safer for maize than atrazine. The results of this study therefore show that compound I [R = Et propanoate] could potentially be used as a post-emergence herbicide for maize fields.
