A regioselective method for the introduction of sulfonyl groups at the gamma-carbon of enone systems is reported. Using a copper catalyst and readily available sulfonyl chlorides, a range of silyl dienol ethers are sulfonylated in good yield under mild reaction conditions. The sulfone derivatives formed are poised for further synthetic manipulations as demonstrated by regioselective alkylations.
