| Abstract: | Twelve isoindol-1,3-dioxo substituted benzoxazine carboxyl esters were designed and synthesized,and their structures were identified by 1H NMR、MS and etc. Bioassay results indicated that some compounds such as 2-(6-(1,3-dioxo-isoindol-2-yl)-7-fluoro-3-oxo-2,3-dihydro-benzb1,4oxazine-4-yl) carboxyl esters (7) exhibited post-emergence herbicidal activity against dicotyledon weeds. Compounds (7a),7b and 7c had more than 80% herbicidal activity against dicotyledon weeds such as Abutilon theophrasti Medic,Chenopodiun album L.,Amaranthus retroflexus L. at 75 g a.i./hm2. |
| Keywords: | benzb1 4oxazine-3(4H)-one isoindol-1 3-dioxo protox-inhibitor synthesis herbicidal activity |
