Liu, Xiaoguang published the artcileCopper-Catalyzed γ-Sulfonylation of α,β-Unsaturated Carbonyl Compounds by Means of Silyl Dienol Ethers, Computed Properties of 21286-54-4, the publication is Organic Letters (2015), 17(14), 3572-3575, database is CAplus and MEDLINE.
γ-Sulfonyl-α,β-unsaturated ketones such as I [R = Ph, 4-MeC6H4, 4-O2NC6H4, 2,4,6-R13C6H2, F5C6, 8-quinolinyl, Me, i-Pr, ClCH2CH2, cyclopropyl, (1S)-10-camphorsulfonyl; R1 = Me, i-Pr; R2 = H] were prepared regioselectively by reaction of dienyl silyl ethers such as II (TBDMS = tert-butyldimethylsilyl) with sulfonyl chlorides RSO2Cl [R = Ph, 4-MeC6H4, 4-O2NC6H4, 2,4,6-R13C6H2, F5C6, 8-quinolinyl, Me, i-Pr, ClCH2CH2, cyclopropyl, (1S)-10-camphorsulfonyl; R1 = Me, i-Pr] in the presence of CuCl in MeCN. Selected sulfonylated unsaturated ketones underwent regioselective alkylation and Michael addition reactions and cyclocondensations to yield products such as I (R = Ph; R2 = Me, MeO2CCH2CH2).
