摘要：

The addition of three nitrones to phenylvinylsulfone, 1, has been studied. The stereochemistry previously established by two-dimensional NMR techniques was confirmed by X-ray crystal structure determination. Theoretical studies made us propose that this reaction is not purely regioselective, but by controlling the substituents of nitrone and temperature the regioselectivity increases.
