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-containingorganic compounds containing at least 4 planar-chiral oraxial-chiral groups, where these planar-chiral or axial-chiralgroups are linked as Schiff's bases to the primary amino groupsof compounds of the formula (I)(R1R1)N-X-N(R1R1) (I)whereR1 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-andR6 is hydrogen,X is an aliphatic and/or aromatic group, which may containheteroatoms,which are suitable as catalysts for asymmetrical homogeneouscatalysis.
