Abstract Compounds of the formula (I) in the form of racemates, enantiomerically pure diastereomers or a mixture of diastereomers, where the radicals R1 are identical or different and are each C1-C4-alkyl; m is 0 or an integer from 1 to 4; n is 0 or an integer from 1 to 3; p is 0 or an integer from 1 to 5; R2 is an aromatic hydrocarbon radical or a C-bonded heterohydrocarbon radical and R3 is an aliphatic or C-bonded heteroaliphatic hydrocarbon radical; R2 and R3 are identical or different and are each an aliphatic or C-bonded heteroaliphatic hydrocarbon radical; R4 is an unsubstituted or C1-C6-alkyl-, C1-C6-alkoxy- or halogen-substituted hydrocarbon radical; and A is a secondary amino group, are ligands for metal complexes which are suitable as catalysts for homogeneous enantioselective hydrogenation.
