Abstract

The determination of the enantiomeric composition of α- 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 19F NMR spectroscopy. A wide variety of target molecules have been studied to highlight the broad applicability of the method. © 2005 Elsevier Ltd. All rights reserved.
