Enantioselective hydrogenation of intermediates in the synthesis of tipranavir

The invention relates to a process for preparing the compounds of general formula I by enantioselective hydrogenation of the compounds of formula II in the presence of special hydrogenation catalysts. The invention is characterised by high enantioselectivity, providing easy access to a category of i...
