Paragraph 0047; 0048; 0053; 0054, (2017/04/28)
The invention provides a preparation method of 2-methoxyimino-2-furyl ammonium acetate. The preparation method includes: enabling a compound of a structure shown as a formula (I) to react with methoxyamine to obtain reaction liquid containing the compound of a structure shown as a formula (II); adding alkali into the reaction liquid to obtain reaction liquid containing a compound of a structure shown as a formula (III); adding ammonium salt into the reaction liquid containing the compound of the structure shown as the formula (III) to obtain 2-methoxyimino-2-furyl ammonium acetate. A target product is obtained by selecting the compound of the structure shown as the formula (I) as a starting raw material, enabling the starting raw material to react with methoxyamino acid and hydrolyzing and ammonifying a reaction product, preparation from the starting raw material to the final product can be completed in a same reaction system, an intermediate of the reaction does not need to be separated, and yield and purity of the reaction are high.

experimental part, p. 9797 - 9800 (2010/02/27)
A novel one-pot synthesis of aryl α-keto esters was developed through oxidation of aryl-ketones using selenium dioxide, esterification accompanied by ketalization, and hydrolysis. Both aromatics and heteroaromatics gave good yields by this one-pot method.
