US5847190A Dendritic nitrogen-containing organic compounds containing planar-chiral or axial-chiral end groups and the preparation and use thereof 失效
含有平面手性或轴向手性端基的树枝状含氮有机化合物及其制备和用途

Dendritic nitrogen-containing organic compounds containing planar-chiral or axial-chiral end groups and the preparation and use thereof
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) (R.sup.1 R.sup.1)N--X--N(R.sup.1 R.sup.1) (I) where 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 --, 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 --, 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 --, 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 --, 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 R.sup.6 is hydrogen, X is an aliphatic and/or aromatic group, which may contain heteroatoms, which are suitable as catalysts for asymmetrical homogeneous catalysis.
