| titleOfInvention | Chiral polyampholyte derivatives of dimethylphosphinic acid, polyalkylene polyamines and phenylalanine and the method of their preparation |
| abstract | The invention relates to chiral polyamolytolytes of dimethylphosphinic acid derivatives, polyalkylene polyamines and phenylalanine, which are intended for use as enantioselectors and diastereoselectors, and complexones for the production of chiral homogeneous and heterogeneous catalysts of the general formula I, in which A denotes a fragment of the dimethylphosphinic acid fragment in polyampolite, while B is a fragment of the polyalkylene polyamine structure in which nip can be the same or different and denote integers from 2 to 12, while q is the number of aminopolyalkene structures and is from 2 to 6, y is the number of polyaminopolyalkene fragments in the polymer, while C denotes a fragment of the phenylalanine structure, and az denotes the number of such fragments in the polyampholite, with the free places of fragment A only binding with the free places in fragment B and C. The invention also discloses a method of producing chiral pol of phospholinic acid derivatives, polyalkylene polyamines and phenylalanine derivatives of the general formula I, which consists in the first stage that one molar part of phosphinic acid is reacted with at least one molar part of formaldehyde and at least two molar parts of -NH- groups to which consists of the sum of -NH- groups derived from a polyalkylene polyamine selected from the group consisting of: 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,5-diaminopentane, 1,6-diaminohexane, 2-methyl-1 , 5-diaminopentane, 1,2-diaminocyclohexane, bis (hexamethylene) triamine, diethylenetriamine, N- (3-aminopropyl) -1,3-diaminopropane, N- (2-aminoethyl) -1,3-diaminopropane, N, N '-bis (3-aminopropyl) ethylenediamine, triethylenetetramine, tetraethylenepentamine and pentaethylenehexamine, and -NH- groups derived from phenylalanine, 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 reacting s of losses and the formation of a chiral polyampholite containing structural fragments of dimethylphosphinic acid, polyalkylene polyamine and phenylalanine, which in the third stage is subjected to a crosslinking of at least 0.5 mol part of formaldehyde. The resulting chiral polyampolite is separated from the reaction mixture by decanting, filtration or centrifugation, optionally by evaporation of volatile components under reduced pressure. |
