The Iodine-mediated oxidative intramolecular amination of anilines via cleavage of unactivated (sp3)C–H and N–H bonds for the production of indolines is described. This transition-metal-free approach provides a straightforward strategy for producing (sp3)C–N bonds for use in the preferential functionalization of unactivated (sp3)C–H bonds over (sp2)C–H bonds. The reaction could be performed on a gram
描述了碘介导的苯胺的氧化分子内胺化反应,该反应通过裂解未活化的(sp 3)C–H和N–H键来产生二氢吲哚。这种无过渡金属的方法为生产(sp 3)C–N键提供了一种简单的策略,用于未活化(sp 3)C–H键相对于(sp 2)C–H键的优先官能化。该反应可以以克为单位进行,以合成官能化的二氢吲哚。
