Halogenated Derivatives of 2h-1,4-benzoxazin-3(4h)-one with C-2 Alkyl Chains Or N-4 Acyl Residues
The invention relates to halogenated derivatives of 2H-1,4-benzoxazin-3(4H)-one with C-2 alkyl chains or N-4 acyl residues. The invention belongs to the field of chemical compounds that can be used for agricultural pest control. The invention comprises a series of chemical compounds, together with the corresponding methods for the preparation thereof and examples of potential uses. These compounds have molecular structures based on natural products with phytotoxic activity and can be used as models in the development of new selective plant protection products that have a low environmental impact and exhibit, as a fundamental characteristic, a 2H-l,4-benzoxazin-3(4H)-one backbone and the presence of heteroatoms on the aromatic ring, and functional groups at position C-2 or N-4 that modulate solubility and increase the phytotoxic activity thereof. The biological properties of the compounds of the invention make it possible to obtain optimum solubility values with a view to optimizing phytotoxic activity, thereby providing a new generation of herbicide models of natural origin.
