Abstract

Wynalazek dotyczy chiralnych poliamfolitów pochodnych kwasu dimetylofosfinowego, polialkilenopoliamin i waliny, które są przeznaczone do stosowania jako enancjoselektory i diastereoselektory, oraz kompleksony do wytwarzania chiralnych katalizatorów homogennych i heterogennych, przedstawionych wzorem ogólnym I. Sposób wytwarzania chiralnych poliamfolitów pochodnych kwasu dimetylofosfinowego, polialkilenopoliamin i waliny o wzorze 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, a y oznacza liczbę fragmentów poliaminopolialkenowych w polimerze, natomiast C oznacza fragment struktury waliny, a z oznacza liczbę takich fragmentów w poliamfolicie, charakteryzuje się tym, że w pierwszym etapie jedną część molową kwasu fosfinowego poddaje się reakcji z co najmniej jedną częścią molową formaldehydu zawartego w substancji wybranej z grupy formalina, trioksan, paraform, 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, tetraerylenopentaminę, 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 waliny, a reakcję prowadzi się w temperaturze 273-373K, w wodzie, w obecności aktywatora w postaci dowolnego kwasu Bronsteda, aż do przereagowania substratów i utworzenia się mieszaniny kwasów aminometylofosfinowych, pochodnych polialkilenopoliamin i waliny, 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 waliny, 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 valine, 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. A method for preparing chiral polyampholytes derivatives of dimethylphosphinic acid, polyalkylene polyamines and valine with the formula general I, in which A is a fragment of the dimethylphosphinic acid structure, x is the number of such fragments in the polyampholyte, and B is a fragment of the polyalkylene polyamine structure, in which n and p may be the same or different and represent integers from 2 to 12, and q is the number of structures aminopolyalkenes and ranges from 2 to 6, and y is the number of polyaminopolyalkene fragments in the polymer, while C is a fragment of the valine structure, and z is the number of such fragments in the polyampholyte, characterized by the fact that in the first step one mole part of phosphinic acid is reacted with at least one mole part of formaldehyde contained in a substance selected from the group formalin, trioxane, paraform, and at least two mole parts of -NH- groups consisting 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, tetraerylenpentamine, 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 from valine, and the reaction is carried out at a temperature of 273-373K, in water, in the presence of an activator in the form of any Bronsted acid, until the substrates are reacted and a mixture of aminomethylphosphinic acids, polyalkylene polyamine derivatives and valine is formed, which in the second stage is cross-linked 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 valine, which in the third step is cross-linked with at least 0.5 mole of formaldehyde, and then the obtained chiral polyampholyte is separated from the post-reaction mixture.
