Abstract:
21,21,21-Trifluoro(aryl)thevinols were synthesized by the reaction of 21,21,21-trifluorothevinone with aryl Grignard reagents. The absolute configuration at C20 atom in these CF3-substituted alcohols can be easily determined by one-dimensional 19F NMR spectroscopy that was verified by X-ray diffraction studies.
