Friedel–Crafts reactions of a sulfonyl-substituted vinylic epoxide with various aromatics

摘要

The phenylsulfonyl-substituted vinylic epoxide 1 was allowed to react with BF3u0001OEt2 and various aromatics. A highlynregioselective but moderately stereoselective mono-Friedel–Crafts reaction occurred which led to products 2n(Table 1). The fluorine-containing compounds 3a–b and 4 were obtained as side products.
