| titleOfInvention |
Process for enantioselective synthesis of single enantiomers of modafinil by asymmetric oxidation |
| abstract |
The invention relates to a method for preparing a sulphoxide compound of formula (I) either as a single enantiomer or in an enantiomerically enriched form, comprising the steps of:n a) contacting a pro-chiral sulphide of formula (II) with a metal chiral complex, a base and an oxidizing agent in an organic solvent; and optionally b) isolating the obtained sulphoxide of formula (I). nn n n n n n n n n n n n wherein n, Y, R 1 , R 1a , R 2 and R 2a are as defined. |
