An efficient and practical method for synthesis of C2‐phosphorylated indoles has been disclosed via a metal‐free 1,2‐phosphorylation of 3‐indolylmethanols with H‐phosphine oxides or H‐phosphonates. This alternative protocol features a broad substrate scope with respect to both 3‐indolylmethanols derived from isatins, acyclic α‐keto amide, α‐keto ester, 1,2‐diketone and simple ketones and H‐phosphine
为C 2磷酸化的吲哚的合成中的高效,实用的方法已公开通过3- indolylmethanols与不含金属的1,2-磷酸ħ膦氧化物或ħ -phosphonates。这种替代协议有广泛的底物范围相对于从靛红衍生的两个3- indolylmethanols,无环α酮酰胺,α酮酯,1,2-二酮和简单酮和ħ -膦氧化物或ħ -phosphonates,中度至高收率和温和的反应条件。机理研究表明,该反应通过 一个不寻常的直接1,2-加成途径,其中3-吲哚基甲醇的羟基附近存在一个吸电子基团起着决定性的作用。
