Aryl groups were introduced into the position β to the nitrogen atom of cyclic amines by carrying out the anodic α-methoxylation of cyclic amine derivatives, the elimination of methanol from the oxidized products, the halomethoxylation of the resulting α,β-unsaturated cyclic amine derivatives, the replacement of the α-methoxy group with an aryl group, and the silver ion-promoted migration of the α-aryl
通过进行环胺衍生物的阳极α-甲氧基化,从氧化产物中除去甲醇,所得α,β-不饱和环胺衍生物的卤代甲氧基化,将芳基引入到环胺氮原子的β位。 ,用芳基取代α-甲氧基,以及银离子促进α-芳基向β位置的迁移。该方法被用于一些生物碱的合成,如(±)-中间膜。
