A novel iodine-catalyzed amidation and imination at the 2α-position of 2,3-disubstituted indoles in the presence of chloramine salts with high regioselectivity has been achieved. The protocol is applicable to a wide range of substrates to deliver the corresponding 2α-nitrogen-containing indole derivatives. Furthermore, to demonstrate the synthetic value of this established transformation, a concise
在氯胺盐存在下具有高区域选择性的新型碘催化酰胺化和2,3-二取代的吲哚在2α-位的胺化反应。该方案适用于多种底物,以递送相应的含2α-氮的吲哚衍生物。此外,为证明此确定的转化的合成价值,已从5个步骤中完成了由2α酰胺化产物制成的akuammiline生物碱的桥接四环骨架的简洁组装。
