DENDRITIC, NITROGEN-CONTAINING ORGANIC COMPOUNDS CONTAINING PLANAR-CHIRAL OR AXIAL-CHIRAL END GROUPS, AND THE PREPARATION AND USE THEREOF

摘要

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) (R1R1)N-X-N(R1R1) (I) where R1 is (R2R2)N-(CH2)2- or (R2R2)N-(CH2)3-, R2 is hydrogen or (R3R3)N-CH2)2- or (R3R3)N-(CH2)3-, R3 is hydrogen or (R4R4)N-(CH2)2- or (R4R4)N-(CH2)3-, R4 is hydrogen or (R5R5)-N-(CH2)2- or (R5R5)N-(CH2)3-, R5 is hydrogen or (R6R6)N-(CH2)2- or (R6R6)N-(CH2)3-and R6 is hydrogen, X is an aliphatic and/or aromatic group, which may contain heteroatoms, which are suitable as catalysts for asymmetrical homogeneous catalysis.
