A new reaction of oxoammonium salt is demonstrated. Addition of oxoammonium salts (1) to electron-rich olefins (2) such as vinyl ethers and enamines rapidly proceeded to give corresponding 1,2-adducts (3) in high yields. The adducts 3 formed were further transformed by treatment with sodium ethoxide to isolable substitution products (4) in one pot reaction.
展示了一种新型的活氧
铵盐反应。向富含电子的烯烃(如
乙烯基醚和烯胺)中加入活氧
铵盐,迅速进行反应,以高产率生成相应的1,2-加合物。接着,通过在反应体系中加入
乙醇钠,这些加合物3被进一步转化,从而在一步反应中得到可分离的取代产物4。
