Highly efficient methods for the one-pot synthesis of beta-substituted enones

A mild and practically-convenient one-pot procedure for the direct beta-substitution of enones has been developed using a conjugate addition-oxidation strategy with a full range of copper- based reagents and N-tert-butylphenylsulfinimidoyl chloride; alkyl-and aryl-substituted enones are delivered in good to excellent yields.
