Rearrangements of aryl- and ethenyl-substituted oxiranes proceed well in the presence of triethylsilane and BF3 to give optically active alcohols, which we have used for a synthesis of (S)-ibuprofen 1. We have also shown that a vinyl group migrates to a benzylic cation faster than a phenyl group migrates to an allyl cation.
