发明名称 New optically-active, homogeneously soluble ligands enlarged by specified polymers and similar ligands are useful in enantioselective reaction, especially dihydroxylation of double bond or asymmetric aminohydroxylation
摘要 In new optically-active, homogeneously soluble ligands (I), enlarged by polymers, with quinine/quinidine-type structure(s) as active units causing chiral induction, the polymer enlargement is selected from polyacrylates, polyvinylpyrrolidinone, polysiloxanes, polybutadienes, polyisoprene, polyalkenes, polystyrenes, polyoxazoline or mixtures of these. In new optically-active, homogeneously soluble ligands (I), enlarged by polymers, with quinine/quinidine-type structure(s) of formula (A) or (B) as active units causing chiral induction, the polymer enlargement is selected from polyacrylates, polyvinylpyrrolidinone, polysiloxanes, polybutadienes, polyisoprene, polyalkenes, polystyrenes, polyoxazoline or mixtures of these. R<1>, R<2> = hydrogen (H), 1-8 carbon (C) alkyl or acyl, 3-8 C cycloalkyl, 6-18 C aryl, 7-19 C aralkyl, 3-18 C heteroaryl, 4-10 C heteroaralkyl, (1-8 C alkyl)1-3-(3-8 C)-cycloalkyl, (1-8 C alkyl)1-3-(6-18 C aryl or (1-8 C alkyl)1-3-(3-18 C)-heteroaryl; R<3> = H; or R<1>, R<2> or R<3> = the bond to the polymer Independent claims are also included for the following: (a) new optically-active, homogeneously soluble ligands (II), enlarged by polymers, with anthraquinone structure(s) (C), 1,4-di-substituted by (A) or (B), as active units causing chiral induction; (b) the preparation of (I) and (II); (c) the use of optically-active, homogeneously soluble ligands (III), enlarged by polymers, with (A), (B) or (C) structure(s), for asymmetric aminohydroxylation of C=C double bonds. R<4> = (A) or (B); R<3> = H or a bond to a polymer enlargement.
