The invention discloses a process for the preparation of compounds having structures typical for proton pump inhibitors in enantiomerically enriched form by using particular metal catalysts in an enantioselective oxidation step. Also disclosed are useful further processes and pure intermediate and subsequently final products.
本发明公开了一种通过使用特定
