    • 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NMR光谱的高通量筛选方法,用于测定显示非对称过程的反应的对映体选择性。 反应可以由手性催化剂,试剂或生物催化剂引起,使得可以评价所述产物的对映体选择性。 在一个实施方案中,使用同位素标记的假对映异构体或假前手性底物,使得对映体选择性可以通过对各个底物和/或产物的NMR信号进行积分来定量。 使用自动设置装置,包括微量滴定板,机器人和高通量NMR装置对于高通量过程是决定性的。 在本发明的第二个实施方案中,设备的自动设置用于以定量方式检测已经以非对映异构体形式的对映异构体纯试剂衍生化的产物和/或离子。 在两个实施方案中,至少可以进行1000次ee测定,其准确度至少为±5%。
