Patent

CA 2599690

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: 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). wherein Ar, Y, R1 are as defined in claim 1.

L'invention concerne un procédé destiné à préparer un composé de sulfoxyde de formule (I) soit en tant qu'énantiomère unique ou sous une forme enrichie sur le plan énantiomère, comprenant les étapes consistant: a) à mettre en contact un sulfure pro-chiral de formule (II) avec un complexe chiral métallique, une base et un agent d'oxydation dans un solvant organique; et éventuellement (b) à isoler le sulfoxyde obtenu de formule (I), Ar, Y, R1 étant tels que définis dans la revendication 1.
