A RhIII‐catalyzed intramolecular redox‐neutral atom‐economic annulation of a tethered alkyne has been developed to efficiently construct 2‐amidealkyl indoles with completely reversed regioselectivity by a CH activation pathway. Furthermore, using the RhIII‐catalyzed CH activation/annulation as a key step, a one‐pot synthesis of pyrido[1,2‐a]indoles has also been developed and applied to a highly
负载Rh III催化的栓系炔的分子内氧化还原中性原子经济环已发展到通过C有效地构造2- amidealkyl吲哚完全的反转区域选择性 ħ活化途径。此外,使用Rh III催化的CH活化/环化为关键步骤,还开发了单锅合成吡啶并[1,2-a]吲哚,并将其应用于(± )-碘精。
