titleOfInvention | A kind of synthetic method of chiral (2S,3R)-p-methylsulfonyl phenylserine |
abstract | The invention discloses a method for synthesizing chiral (2S,3R)-p-methylsulfonyl phenylserine, belonging to the technical fields of chemical industry and pharmacy. The synthesis method comprises the following steps: an enzyme-catalyzed condensation reaction and an oxidation reaction; the The method for the enzyme-catalyzed condensation reaction is as follows: adding 4-methylsulfoxide benzaldehyde, phosphate buffer, L-threonine, pyridoxal phosphate aqueous solution, and transaldolase into a reaction vessel, reacting in a water bath at 30° C., and reacting After 6-8h, a primary product is obtained; in the oxidation reaction, hydrogen peroxide is added to the primary product, the temperature is raised to 40 ° C, and a product solution is obtained after the reaction for 2 h; in the oxidation reaction, hydrogen peroxide is added to the primary product, and the temperature is raised to 40 ° C. , after the reaction for 2h, a chiral (2S,3R)-p-methylsulfonylphenylserine solution is obtained; the present invention can improve the reaction conversion rate and the concentration of the target product, and reduce the post-processing cost of the reaction. |
