Abstract (en)
[origin: CA2520129A1] The invention relates to a method for producing the compounds of general formula (I) by the enantioselective hydrogenation of compounds of formula (I I) in the presence of special hydrogenation catalysts. The invention is characterised by a high enantioselectivity, enabling a substance class of important medicaments to be obtained in a simple manner.
