Abstract[English]
positions are chiral centers, both in the R configuration or the S configuration. The catalyst of the present invention exhibits an excellent effect in catalyzing the asymmetric oxidation of thioether compounds to prepare sulfoxide compounds as single enantiomers or in an enantiomerically enriched form, produces target compounds with a high purity and a high yield, and is applicable to industrial production.[French]
étant des centres chiraux, à la fois dans la configuration R ou dans la configuration S. Le catalyseur selon la présente invention présente un excellent effet dans la catalyse de l'oxydation asymétrique de composés thioéther pour préparer des composés sulfoxyde en tant qu'énantiomères uniques ou sous une forme énantiomériquement enrichie, produit des composés cibles ayant une pureté élevée et un haut rendement, et est applicable à la production industrielle.[Chinese]
处为手性中心，均为R构型或均为S构型。本发明所述催化剂在催化硫醚类化合物的不对称氧化制备单一的对映异构体或对映异构体富集形式的亚砜类化合物上效果优异，目标化合物具有高纯度和高收率，适于工业化生产。
