The invention relates to a high-throughput screening method based on NMR spectroscopy for determining the enantioselectivity of reactions which show an asymmetric course. The reactions can be caused by chiral catalysts, agents, or biocatalysts such that said products can be evaluated regarding the enantioselectivity thereof. In one embodiment, isotope-marked pseudo-enantiomers or pseudo-prochiral substrates are used such that the enantioselectivity can be quantified by integrating the NMR signals of the respective substrates and/or products. The use of an automated setup of devices, including microtiter plates, robots, and high-throughput NMR devices, is decisive for the high-throughput process. In a second embodiment of the invention, the automated setup of devices is used to detect in a quantitative manner the products and/or educts that have been derivatized with enantiomer-pure agents in the form of diastereomers. At least 1000 ee determinations can be done per day with accuracy of at least ±5 percent in both embodiments.
本发明涉及一种基于核磁共振光谱的高通量筛选方法,用于确定显示不对称过程的反应的对映体选择性。这些反应可以由手性催化剂、药剂或
生物催化剂引起,从而可以对上述产物的对映选择性进行评估。在一个实施方案中,使用了同位素标记的假对映体或假手性底物,这样就可以通过整合各自底物和/或产物的核磁共振信号来量化对映选择性。使用自动化装置,包括微量滴定板、机器人和高通量 NMR 装置,对高通量过程具有决定性意义。在本发明的第二个实施方案中,自动装置用于定量检测用对映体纯化剂衍生出的非对映体形式的产物和/或衍
生物。在这两个实施例中,每天至少可进行 1000 次ee测定,精度至少为±5%。
