| 20110059850 | PHYTOTOXIC HALOGENATED DERIVATIVES OF BENZOXAZINONES - The invention relates to phytotoxic halogenated derivatives of benzoxazinones. The aim of the invention relates to the production of novel phytosanitary products that are suitable for agricultural weed control, based on natural chemical substances. The invention comprises novel chemical compounds having high levels of phytotoxic activity and the preparation methods thereof. Said substances are derived from natural products with the 1,4-benzoxazin-3-one skeleton involved in different chemical defense interactions in plants. The inventive compounds have suitable phytotoxic activity levels for use in weed control and for use as stable models for the development of novel phytosanitary products based on the 1,4-benzoxazin-3-one skeleton. | 03-10-2011 |
