Rh-catalyzed C–H carbonylation of indoles under 1 atm of CO has been achieved. Various substituted indoles and indole with free N–H could be carboxylated with linear- and/or cyclic-alcohol to give the desired indole-3-carboxylates with up to 92% yield. A mechanism involving RhIII initiated C–H metallation is proposed.

A novel and efficient double-carbonylation of indoles with primary or secondary amines to yield indole-3-α-ketoamides has been developed and bioactive molecules could be one-pot synthesized using the current methodology, which could also be selectively switched to mono-carbonylation to afford indole-3-amides only by a slight modification of reaction conditions.
