Page/Page column 22, (2008/06/13)
The present invention relates to a process for the preparation of quartenary ammoniumsalts of esomeprazole. Further, the present invention also relates to the use quartenary ammoniumsalts of esomeprazole for the treatment of gastrointestinal disorders, pharmaceutical compositions containing them as well as the quartenary ammoniumsalts of esomeprazole, as such.

Good regioselectivity and chirality transfer for aryl-substituted allyl units is achieved in allylic alkylations with a wide range of nucleophiles by using the highly active ruthenium catalyst 1. This method provides a route to antidepressants such as (-)-fluoxetine from (S)-ephedrine (see scheme; Cp* = η5-C5Me5, TBAT = tetrabutylammonium triphenyldifluorosilicate).
