Publication number: 20050153358Abstract: 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.Type: ApplicationFiled: February 22, 2003Publication date: July 14, 2005Applicant: Studiengesellschaft Kohle mbHInventors: Manfred Reetz, Patrick Tielmann, Andreas Eipper, Richard Mynott
