Directed metallation of the diethoxymethyl protected indole 4 followed by treatment with β-nitrostyrene leads to the 1,2-disubstituted indole 5. Using 5 as a central intermediate, the tricyclic annellation products of type 2 and 3 were accessed when the regiochemical outcome of the reactions could be controlled.
二乙氧基甲基保护的吲哚 4 的定向金属化,然后用 β-硝基苯乙烯处理,得到 1,2-二取代吲哚 5。使用 5 作为中心中间体,当 2 型和 3 型的三环环化产物的区域化学结果被获取时反应是可以控制的。
