The reaction of 3,6-dimethoxy-3,6-dimethylcyclohexa-1,4-diene (1) with an excess of different silyl enol ethers derived from ketones in the presence of zinc dichloride leads to the corresponding ketones regioselectively arylated at the α position.
3,6-二甲氧基-3,6-二甲基环己-1,4-二烯(1)与过量的由酮衍生的不同甲硅烷基烯醇醚在二氯化锌存在下的反应导致相应的酮在α处区域选择性芳基化位置。
