Paragraph 0036-0037, (2020/12/29)
The invention relates to a preparation method of N-(aryl/heteroaryl)alkyl- diamide, which comprises the following steps: under the protection of nitrogen, sequentially adding transition metal, phosphine or nitrogen ligand, cocatalyst, alkali, solvent, Nhalogenated cyclodiamide, alkyl aromatic ring or alkyl heteroaromatic ring compound into a reaction container, carrying out oxidative amination reaction at 80-140 DEG C, and till the reaction concludes after 6-48 hours, evaporating and drying a solvent and carrying out column chromatography separation to obtain an N (aryl/heteroaryl) alkyl diamide compound. The invention is simple in synthesis process, mild in reaction condition, high in yield and easy to industrialize.

A series of novel 2-cyanoacrylates containing different aromatic rings were synthesized, and their structures were characterized by 1H NMR, elemental analysis, and single-crystal X-ray diffraction analysis. Their herbicidal activities against four weeds and inhibition of photosynthetic electron transport against isolated chloroplasts (the Hill reaction) were evaluated. Both in vivo and in vitro data showed that the compounds containing benzene, pyridine, and thiazole moieties gave higher activities than those containing pyrimidine, pyridazine, furan, and tetrahedronfuran moieties. To further explore the comprehensive structure-activity relationship on the basis of in vitro data, comparative molecular field analysis (CoMFA) was performed, and the results showed that a bulky and electronegative group around the para-position of the aromatic rings would have the potential for higher activity, which offered important structural insights into designing highly active compounds prior to the next synthesis.
