A kind of preparation method of (E)-2-(2-tolyl)-2-methoxyimino methyl acetate |
| abstract |
The invention provides a preparation method of (E)-2-(2-tolyl)-2-methoxyiminoacetic acid methyl ester, (Z)-2-(2-tolyl)-2-methoxy Methyl iminoacetate or (E/Z)-2-(2-tolyl)-2-methoxyiminomethyl acetate or containing (E/Z)-2-(2-tolyl)-2 -The mother liquor of methyl methoxyiminoacetate and alkali generate saponification reaction to obtain (E)-2-(2-tolyl)-2-methoxyiminoacetic acid, under alkaline conditions, the obtained ( E)-2-(2-Tolyl)-2-Methoxyiminoacetic acid reacts with methylating reagent to obtain (E)-2-(2-Tolyl)-2-Methoxyiminoacetic acid methyl ester . The method of the invention realizes the transformation from the Z configuration to the E configuration product, so that the yield of the obtained E configuration product is significantly improved, the corrosion to equipment is small, and environmental pollution is not easily caused, and it is an environmentally friendly chemical synthesis process. |
