A combination of LiO‐tBu, CsF, and 18‐crown‐6 can be used to carboxylate indole derivatives at the C‐2 position under an ambient CO2 atmosphere. Substrates bearing an electrophilic substituent (i.e. CN, formyl, benzoyl, phenylsulfonyl, phenylsulfinyl, and chloride) at the C‐3 position are smoothly converted into their corresponding carboxylated products with high functional group compatibility.

An unprecedented synthesis of polysubstituted indole-fused pyridazines (azacarbolines) from α-indolylhydrazones under oxidative conditions using a combination of iodylbenzene (PhIO2) and trifluoroacetic acid (TFA) has been developed. This transformation is conducted without the need for transition metals, harsh conditions, or an inert atmosphere.

formal [3 + 2]-annulation reactions of indoles and electrophilic enol carbenes. High enantioselectivity and exclusive regiocontrol occurred with enoldiazoacetamides using a less sterically encumbered prolinate-ligated dirhodium(II) catalyst in reactions with N-substituted indoles without substituents at the 2- or 3-positions via a selective vinylogousaddition process. In this transformation, donor–acceptor
