Dimethylsulfonium methylide undergoes S(N)2' addition/1,2-elimination with epoxy vinyl sulfones to generate enantiopure six and seven membered cross-conjugated hydroxy vinyl sulfones. Moderate to excellent yields were obtained for both six and seven membered substrates.
二甲基s亚甲基与环氧乙烯基砜进行S(N)2'加成/ 1,2-消除,生成对映体纯的六元和七元交叉共轭羟基乙烯基砜。对于六元和七元基板,均获得了中等至极好的产量。
