C3–N1′ bond formation of bisindoles has been a great challenge due to the intrinsic reactivity of indoles as both C3 and N1-nucleophilic character. Herein, we demonstrate an C3–N1′ cross-coupling reaction of indoles using N-methoxyindoles as

We report herein a formal cine-substitution/hydrolysis of 3-azidoindoles generated from 3-azido-2-methoxyindolines (AZINs). This protocol enables the introduction of various carboxylic acids and alcohols into indolin-3-ones at the C2-position, afford

Echinosulfonic acid D, a sponge metabolite whose structure was recently reassigned, was synthesized for the first time. The key step is the double indolization of dimethylbarbituric acid using the umpolung indole reagent, followed by a hydrolysis/dec

Use of 3-azidoindoles in organic synthesis remains a difficult task owing to their instabilities. Herein, we report a general and concise approach for tackling this problem by using 3-azidoindole surrogates. The surrogates are bench-stable, presumabl

This work reports the novel reactivity of hemiaminal as a precursor for indole editing at the multi-site. The HFIP-promoted indole editing of indoline hemiaminals affords 2-arylindoles through a ring-switch sequence. The key to success of this transf

The regioselective synthesis of both 2- and 3-alkoxyindoles from a common intermediate, 2-alkoxy-3-bromoindolines (ROBIN), is described. The 2-alkoxyindoles are obtained by a base-promoted regioselective elimination of HBr from ROBIN, whereas the syn

2,3-Dimethoxyindolines (DiMeOINs) have emerged as a latent electrophile in indium-catalyzed SNAr reactions. They are easily obtained from commercially available indoles and allowed access to 3-substituted indoles. The reaction proceeds via SNAr react

We disclose a silver-mediated intramolecular Friedel–Crafts-type cyclization of 2-benzyloxy-3-bromoindolines to afford an untapped family of isochromeno[3,4-b]indolines and 3-arylindoles, in which deformylative arylation of 2-(4-methoxybenzyloxy)-3
