2-Aryl-2-fluoropropionic acids were prepared by treatment of either ethyl α-hydroxy-carboxylates or cyanohydrin O-silyl ethers with diethylaminosulfur trifluoride and subsequent hydrolysis. The methylester of 2-fluoro-2-(4-isobutylphenyl)propionic acid (“α-fluoroibuprofen”) was submitted to an enzymatic racemate resolution.
