Abstract

Wynalazek dotyczy chiralnych poliamfolitów pochodnych kwasu dimetylofosfinowego, polialkilenopoliamin i leucyny, izoleucyny lub norleucyny, które są przeznaczone do stosowania jako enancjoselektory i diastereoselektory, oraz kompleksony do wytwarzania chiralnych katalizatorów homogennych i heterogennych, przedstawionych wzorem ogólnym I. Wynalazek dotyczy również sposobu wytwarzania chiralnych poliamfolitów pochodnych kwasu dimetylofosfinowego, polialkilenopoliamin i leucyny, izoleucyny lub norleucyny, przedstawionych wzorem ogólnym I, w którym A oznacza fragment struktury kwasu dimetylofosfinowego, x oznacza liczbę takich fragmentów w poliamfolicie, natomiast B oznacza fragment struktury polialkilenopoliaminy, w którym n i p mogą być takie same lub różne i oznaczają liczby całkowite od 2 do 12, natomiast q jest liczbą struktur aminopolialkenowych i wynosi od 2 do 6, y oznacza liczbę fragmentów poliaminopolialkenowych w polimerze, natomiast C oznacza fragment struktury leucyny, a z oznacza liczbę takich fragmentów w poliamfolicie, który polega na tym, że w pierwszym etapie jedną część molową kwasu fosfinowego poddaje się reakcji z co najmniej jedną częścią molową formaldehydu i co najmniej dwiema częściami molowymi grup -NH-, na które składa się suma grup -NH- pochodzących od polialkilenopoliaminy wybranej z grupy obejmującej bis(heksametyleno)triaminę, dietylenotriaminę, N-(3-aminopropylo)-1,3-diaminopropan, N-(2-aminoetylo)-1,3-diaminopropan, N,N'-bis(3-aminopropylo)etylenodiaminę, trietylenotetraminę, tetraetylenopentaminę, pentaetylenoheksaminę, 1,2-diaminoetan, 1,3-diaminopropan, 1,4-diaminobutan, 1,5-diaminopentan, 1,6-diaminoheksan, 2-metylo-1,5-diaminopentan i 1,2-diaminocykloheksan i grup -NH- pochodzących od leucyny, izoleucyny lub norleucyny, a reakcję prowadzi się w temperaturze 273-373 K, w wodzie, w obecności aktywatora w postaci dowolnego kwasu Bronsteda, aż do przereagowania substratów i utworzenia się mieszaniny kwasów aminometylofosfinowych, pochodnych polialkilenopoliamin i leucyny, izoleucyny lub norleucyny, którą w drugim etapie poddaje się usieciowaniu co najmniej jedną częścią molową formaldehydu w obecności aktywatora w postaci dowolnego kwasu Bronsteda aż do przereagowania substratów i utworzenia się chiralnego poliamfolitu zawierającego fragmenty strukturalne kwasu dimetylofosfinowego, polialkilenopoliaminy i leucyny, izoleucyny lub norleucyny, który w trzecim etapie poddaje się dosieciowaniu co najmniej 0,5 części molowej formaldehydu, po czym tak otrzymany chiralny poliamfolit wydziela się z mieszaniny poreakcyjnej.The invention relates to chiral polyampholytes derivatives of dimethylphosphinic acid, polyalkylene polyamines and leucine, isoleucine or norleucine, which are intended for use as enantioselectors and diastereoselectors, and complexes for the preparation of chiral homogeneous and heterogeneous catalysts, represented by the general formula I. The invention also relates to a method for preparing chiral polyampholytes of acid derivatives. dimethylphosphinic acid, polyalkylene polyamines and leucine, isoleucine or norleucine, represented by the general formula I, in which A is a fragment of the structure of dimethylphosphinic acid, x is the number of such fragments in the polyampholyte, and B is a fragment of the polyalkylene polyamine structure, where n and p may be the same or different and mean integers from 2 to 12, while q is the number of aminopolyalkene structures and ranges from 2 to 6, y means the number of polyaminopolyalkene fragments in the polymer, while C means a fragment of the leucine structure, and z means the number of such fragments in the polyampholyte, which means that in in the first step, one mole part of phosphinic acid is reacted with at least one mole part of formaldehyde and at least two mole parts of -NH- groups, which consist of the sum of -NH- groups derived from a polyalkylene polyamine selected from the group consisting of bis(hexamethylene)triamine, diethylenetriamine, N-(3-aminopropyl)-1,3-diaminopropane, N-(2-aminoethyl)-1,3-diaminopropane, N,N'-bis(3-aminopropyl)ethylenediamine, triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine, 1 ,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,5-diaminopentane, 1,6-diaminohexane, 2-methyl-1,5-diaminopentane and 1,2-diaminocyclohexane and -NH- groups derived from leucine, isoleucine or norleucine, and the reaction is carried out at a temperature of 273-373 K, in water, in the presence of an activator in the form of any Bronsted acid, until the reactants are reacted and a mixture of aminomethylphosphinic acids, polyalkylene polyamine derivatives and leucine, isoleucine or norleucine is formed, which, in the second step, is cross-linked with at least one mole of formaldehyde in the presence of an activator in the form of any Bronsted acid until the substrates are reacted and a chiral polyampholyte is formed containing structural fragments of dimethylphosphinic acid, polyalkylene polyamine and leucine, isoleucine or norleucine, which in the third step is subjected to cross-linking with at least 0.5 mole of formaldehyde, after which the chiral polyampholyte thus obtained is separated from the post-reaction mixture.
