Abstract

The present invention relates to dendritic, nitrogen-containing organic compounds containing at least 4 planar-chiral or axial-chiral groups, where these planar-chiral or axial-chiral groups are linked as Schiff's bases to the primary amino groups of compounds of the formula (I) EQU (R.sup.1 R.sup.1)N--X--N(R.sup.1 R.sup.1) (I) where PA1 R.sup.1 is (R.sup.2 R.sup.2)N--(CH.sub.2).sub.2 -- or (R.sup.2 R.sup.2)N--(CH.sub.2).sub.3 --, PA1 R.sup.2 is hydrogen or (R.sup.3 R.sup.3)N--CH.sub.2).sub.2 -- or (R.sup.3 R.sup.3)N--(CH.sub.2).sub.3 --, PA1 R.sup.3 is hydrogen or (R.sup.4 R.sup.4)N--(CH.sub.2).sub.2 -- or (R.sup.4 R.sup.4)N--(CH.sub.2).sub.3 --, PA1 R.sup.4 is hydrogen or (R.sup.5 R.sup.5)--N--(CH.sub.2).sub.2 -- or (R.sup.5 R.sup.5)N--(CH.sub.2).sub.3 --, PA1 R.sup.5 is hydrogen or (R.sup.6 R.sup.6)N--(CH.sub.2).sub.2 -- or (R.sup.6 R.sup.6)N--(CH.sub.2).sub.3 -- and PA1 R.sup.6 is hydrogen, PA1 X is an aliphatic and/or aromatic group, which may contain heteroatoms, which are suitable as catalysts for asymmetrical homogeneous catalysis.
