Abstract[English]
The present invention relates to the field of pharmaceutical chemistry, and relates to a method for preparing an α-chiral carboxylic acid and/or an α-chiral ester by means of enzyme catalysis. Specifically, the present invention provides a method for preparing a compound of formula II (α-chiral carboxylic acid) and/or a compound of formula III (α-chiral ester). The method has technical advantages such as high efficiency and high chiral purity of a product.[French]
La présente invention concerne le domaine de la chimie pharmaceutique, et concerne un procédé de préparation d'un acide carboxylique alpha-chiral et/ou d'un ester alpha-chiral par catalyse enzymatique. Plus particulièrement, la présente invention concerne un procédé de préparation d'un composé de formule II (acide carboxylique alpha-chiral) et/ou d'un composé de formule III (ester alpha-chiral). Le procédé présente des avantages techniques tels qu'une efficacité élevée et une pureté chirale élevée d'un produit.[Chinese]
