Rh^III‐catalyzed site selective C4‐alkylation and C2‐annulation of indole derivative has been developed by using variable diazo esters. Fine tuning of the reactivity of diazo esters leads to control in regioselectivity with wide scope and functional‐group tolerance. A straightforward approach has been established to furnish an indolopyridone scaffold.

铑（III）催化的区域选择性直接C4烷基化和吲哚的C2环化反应：直接获得吲哚并吡啶酮

通过使用可变的重氮酯开发了Rh ^III催化的吲哚衍生物的位点C4烷基化和C2环化。对重氮酯反应性的微调可以控制区域选择性，具有宽范围和官能团耐受性。已经建立了一种简单的方法来提供吲哚并吡啶酮支架。
