Dendritic nitrogen-containing organic compounds with planar-chiral or axial-chiral end groups, their preparation and use

摘要

Dendritic nitrogenous organic compounds (A) are new. (A) have at least 4 planar-chiral or axial-chiral groups, which are linked as Schiff's bases with the primary amino groups of a compound of formula X-ÄN(R1)2Ü2 (I). R1 = (CH2)aN(R2R2); R2 = H or (CH2)aN(R3R3); R3 = H or (CH2)aN(R4R4); R4 = H or (CH2)aN; R5 = H or (CH2)aN; n = 2 or 3; R6 = H; X = Phe', Phe'-Y-Phe', Cyc', Phe'-Y-Phe' (sic), -(CH2)n-, -(CH2)a-NR11-(CH2)a-, 2-20 C alkylene or -(CH2)l-ÄO-(CH2)kÜm-O-(CH2)l)-; Phe' = 1,4-phenylene, optionally mono- to tetra-substituted by 1-6 C alkyl; Cyc' = 1,4-cyclohexylene, optionally mono- to tetra-substituted by 1-6 C alkyl; Y = CR7R9, O, C=O or SO2; R7, R9 = H or 1-6C alkyl; n = 2-20; l, k = 2-6; m = 1-40; R11 = 1-20 C alkyl, 2-20 C dialkylamino-(2-10 C)-alkyl, 1-10 C alkoxy-(2-10 C)-alkyl, 2-20 C hydroxyalkyl, 3-12 C cycloalkyl, 4-2 0 C cycloalkyl-alkyl, 2-20 C alkenyl, 4-30 C dialkylamino-alkenyl, 3-30 C alkoxy-alkenyl, 3-20 C hydroxyalkenyl, 5-20 C cycloalkyl-alkenyl, aryl or 7-20 C aralkyl (both optionally mono- to penta-substituted by 1-8 C alkyl, 2-8 C dialkylamino, 1-8 C alkoxy, OH, 3-8 C cycloalkyl or 4-12 C cycloalkyl-alkyl); or R11+R11 = alkylene (optionally interrupted by N or O), e.g. ethylene oxide, propylene oxide, butylene oxide and -CH2-CH(CH3)-O- or polyisobutylene with 1-100 isobutylene units.
