A wide range of silyl enol ethers undergo the reactions with N,N-dimethylanilines in the presence of transition metal catalysts under mild conditions to give β-arylamino ketones. In the cases of silyl enol ethers derived from unsymmetrical ketones, regiospecific addition of carbonyl compounds was obtained at the olefinic position of silyl enol ether.
在过渡金属催化剂存在下,各种甲硅烷基烯醇醚在温和条件下与N,N-二甲基苯胺进行反应,得到β-芳基氨基酮。在衍生自不对称酮的甲硅烷基烯醇醚的情况下,在甲硅烷基烯醇醚的烯烃位置获得了羰基化合物的区域特异性加成。
