The 2 - hydroxy malonic cyanogen synthesis method of α - hydroxy amide

-

Paragraph 0026; 0027; 0028, (2016/10/10)

The invention relates to synthesis of alpha-oxyamide through reaction of 2-hydroxy propylene cyanide as well as corresponding aldehyde or ketone and amine, which mainly solves the problems that the preparation of common alpha-oxyamide has a plurality of reaction steps, the reaction operation is complicated, the reaction cost is high, the post treatment is a trouble, and the like. According to the method, 2-hydroxy propylene cyanide as well as corresponding aldehyde or ketone and amine are directly mixed, methanol or acetonitrile is taken as the solvent, and the product can be obtained by stirring for 10-120 minutes. The method for synthesizing alpha-oxyamide is safe and efficient.
