| titleOfInvention | Process for preparing chiral sulphoxides |
| abstract | A process for preparing single enantiomers of chiral sulphoxides is provided. The process involves (a) reacting an achiral sulphur-containing, e.g. a disulphide, with a single enantiomer of a chiral template having the formula T--(CO)--CH 2 R 1 , wherein T is suitably (eta 5 --C 5 H 5 )Fe(CO)(PPh 3 )-- (Ph=phenyl) and (b) thereafter sterospecifically oxidizing the sulphur atom with an oxidizing agent. A single enantiomer of the chiral sulphoxide can then be generated by reacting the oxidized product with a carbanion. In a preferred embodiment the reaction mixture is thereafter treated with further achiral sulphide to provide a process which is catalytic on the chiral template. |
