-
Paragraph 0069; 0071, (2016/10/09)
An aryloxy anilino propionic ester compound comprises the structure shown in the general formula (I), wherein Ar is aromatic heterocycle or fused heterocycle. Please see the specification for the chemical formula of the aromatic heterocycle and the chemical formula of the fused heterocycle, wherein R1, R2, R3 and R4 are one or more of H, halogen, nitro, methoxy group, methyl, methyl formate group, cyanogroup and trihalomethyl, R5 is the alkyl group on the linear chain or branched chain of H and C1-C4, hydrogen on the alkyl group is substituted by hydroxyl, carboxyl, mercapto group, amino, guanidyl and phenyl, and R6 is one of methyl, ethyl, butyl and the substance specified in the specification. The compound has the advantages that the characteristics of being efficient, capable of acting quickly and not prone to resistance generation of (aryloxy) phenoxypropionate herbicides can be maintained, amino acid functional groups in molecules can be designed to serve as adulterate amino acid so as to restrain the biosynthesis of protein of plants, and all weeds can be controlled.

2,x-Dihalopyridines reacted with phenols catalyzed by CuI/TMEDA in the presence of Cs2CO3 in DMSO at 110 °C under nitrogen atmosphere for 24 h to afford 2-aryloxypyridines in good to high yields except p-nitrophenol. To expand this methodology, a vanilloid receptor ligand used in treatments was prepared in good yield. This method has potential utility in the synthesis of pharmaceuticals, agrochemicals and even natural products.
