Paragraph 0032-0034, (2016/11/09)
The invention relates to synthesis of alpha-hydroxy carboxylic ester with 2-hydroxy propylene cyanide and corresponding aldehyde or ketone. The existing common alpha-hydroxy carboxylic ester generally needs superior cyan such as trimethylsilyl cyanide, and then hydrolysis is carried out on the cyan, so that the reaction operation is relatively complicated, and post treatment is a trouble. According to the method, 2-hydroxy propylene cyanide and corresponding aldehyde or ketone are mixed directly, 4-dimethylamino-pyridne of the catalysis amount is added, alcohol compound is taken as the solvent, and the product can be obtained by stirring for 10-120 minutes. The method for synthesizing the alpha-hydroxy carboxylic ester is safe and has high efficiency.
