Background of invention
Stereoisomer refers to those molecules that atom wherein only spatially differs from one another on arrangement mode.Stereoisomer is generally divided into diastereoisomer or enantiomter; The latter comprises each other the relation for mirror image, and the former is not for being those of mirror image.Enantiomter (mirror image), claims again optical isomer, has identical physics and chemistry character.Therefore, the mixture of enantiomter can not be separated by common separation method conventionally, and common separation method is as fractionation (boiling point is identical); As traditional crystallization, except non-solvent is optically active (because solubility is identical); As traditional chromatogram, unless adsorbent has optical activity (because they are identical for common adsorbent suction-operated).In fact,, because traditional synthetic technology almost always produces the mixture of enantiomter, therefore, the problem that separates enantiomter becomes further serious.Therefore, the separation of the mixture of enantiomter is challenging problem of tool in analytical chemistry.
For organic compound, as amino acid, medicine, agricultural chemicals, agrochemical, the separation of enantiomter is very important, because major part is to have optically actively in them, and exists in pairs as optical isomer (enantiomter).Between the enantiomter of many chiral drugs, aspect biology and pharmacological property, there is significant difference.An enantiomter may have pharmaceutically active, and other may be inertia or even harmful, for example, (S)-Verapamil ((S)-verapamil) is effective calcium channel blocker, and (R)-Verapamil has cardiac side effects, the activity of the l-enantiomter of receptor blocking agent Propranolol (propranolol) is more than its d-type~100 times, (R) (+)-enantiomter of Thalidomide (thalidomide) has the effect of sleeping, and its (S) (-)-enantiomter has teratogenesis, the difference of finding the pharmacologically active of Thalidomide has been used medicine and has caused neonate to occur that severe deformities (" the Thalidomide tragedy " of nineteen sixties etc.) is responsible at period of gestation for women.Therefore, " Food and Drug Administration (The United States Food and Drug Administration) " promulgated the marketing of new regulation management chiral drug recently.According to new regulation, the pharmacological property of each enantiomter to chiral drug should be carried out separately efficacy and saferry test.
Known have the separation of several different methods for enantiomter, for example application of diastereoisomer fractionation, enzymic catalytic reaction, chromatography, liquid film, molecular recognition technology and an inclusion compounding technique.Preferential crystallisation, diastereoisomer splits, and enzymic catalytic reactions etc., are combined and convert them to diastereoisomer with an auxiliary chiral reagent thereby relate to enantiomter, then can be by any conventional isolation technics separately.Relevant diastereoisomer splits, referring to " CRC Handbook ofOptical Resolutions via Diasteromeric Salt Formation " Kozma D., 2002ISBN:0849300193.The major defect that diastereoisomer splits is to need a large amount of pure derivating agents of optically-active (chiral reagent or solvent), and they are expensive and conventionally cannot reclaim.
Can reference color spectral technology (GC, HPLC, CE etc.), it is described in, and " Chiral Separation Techniques-A Practical Approach is " in the second edition, G.Subramanian chief editor, ISBN3-527-29875-4, wherein chromatographic process require suitable chiral selector be attached to fixing mutually in (chiral stationary phase) or be coated in the surface (chirality coated stationary phase) of column material.The enantioselectivity chiral chromatographic column with chiral stationary phase is expensive, and working life is limited, and therefore, the cost of separation is quite high.

Enantioselectivity polymer film described in prior art is as detailed above all asymmetric dense film, and these films are to use chiral polymer as polysaccharide and derivative, poly-a-amino acid, and Polyacetylene Derivatives etc. are manufactured.These polymer great majority are crystal form under field conditions (factors), do not have film and form ability.Thereby the film that uses these polymer to prepare is fragile, thereby be difficult to process.Poor mechanical performance causes their use to be limited to the separation of dialysis mode.In dialysis clastotype, driving force is only solute concentration gradient, and therefore, these films show low-down infiltration rate.Other type stage enantiomer separation film is made with achiral polymer, and these polymer have the enantiomter identification molecule of grafting, that is, and and amino acid, protein, oligopeptides etc.These films have compared with high-mechanical property, become rapidly saturated but be fixed on film in polymeric matrix at infiltration recognizing site, thus As time goes on this film selectively sharply decline.
