摘要
The determination of the enantiomeric composition of alpha-trifluoromethylated-hydroxyl compounds using cinchona alkaloids as chiral selectors is described. The interaction between the alkaloid and trifluoromethylated-hydroxyl compounds converted the enantiotopic nuclei to diastereotopic nuclei observed by F-19 NMR spectroscopy. A wide variety of target molecules have been studied to highlight the broad applicability of the method. (c) 2005 Elsevier Ltd. All rights reserved.
