Unreactive CH to attractive CN: A palladium‐catalyzed intramolecular direct amidation of unactivated C(sp3)H bonds combines CH activation and CN bond formation into one efficient process. Under the optimized conditions, an extraordinary tolerance of functional groups was observed, and numerous indoline derivatives were formed (see scheme).
非反应性Ç H至优厚 Ñ:未活化℃的钯催化的分子内酰胺化直接(SP 3) H键联合Ç ħ活化和C N键的形成为一个有效的方法。在优化的条件下,观察到官能团的非凡耐受性,并形成了许多二氢吲哚衍生物(参见方案)。
