The present invention relates to an analytical method that includes providing a sample potentially containing a chiral analyte that can exist in stereoisomeric forms, and providing a probe selected from the group consisting of coumarin-derived Michael acceptors, dinitrofluoroarenes and analogs thereof, arylsulfonyl chlorides and analogs thereof, arylchlorophosphines and analogs thereof, aryl halophosphites, and halodiazaphosphites. The sample is contacted with the probe under conditions to permit covalent binding of the probe to the analyte, if present in the sample; and, based on any binding that occurs, the absolute configuration of the analyte in the sample, and/or the concentration of the analyte in the sample, and/or the enantiomeric composition of the analyte in the sample is/are determined. The probe may be a coumarin-derived Michael acceptor, a di nitrofluoroarene or analog thereof, an arylsulfonyl chloride or analog thereof, an arylchlorophosphine or analog thereof, an aryl halophosphite, or a halodiazaphosphite.
本发明涉及一种分析方法,包括提供一个潜在含有手性分析物的样品,该手性分析物可以存在于立体异构体形式中,并提供从香豆素衍生的Michael受体、二硝基氟芳烃及其类似物、芳基磺酰氯及其类似物、芳基氯代膦及其类似物、芳基卤代膦酸酯和卤代二氮磷酸酯组成的探针中选取的探针。将样品与探针在条件下接触,以允许探针与分析物共价结合,如果样品中存在分析物;基于发生的任何结合,确定样品中分析物的绝对构型,和/或样品中分析物的浓度,和/或样品中分析物的对映体组成。探针可以是香豆素衍生的Michael受体、二硝基氟芳烃或其类似物、芳基磺酰氯或其类似物、芳基氯代膦或其类似物、芳基卤代膦酸酯,或卤代二氮磷酸酯。
