C7−H‐functionalized indoles are ubiquitous structural units of biological and pharmaceutical compounds for numerous antiviral agents against SARS‐CoV or HIV‐1. Thus, achieving site‐selective functionalizations of the C7−H position of indoles, while discriminating among other bonds, is in high demand. Herein, we disclose site‐selective C7−H activations of indoles by ruthenium(II) biscarboxylate catalysis
A Direct Access to 7-Aminoindoles via Iridium-Catalyzed Mild C–H Amidation of <i>N</i>-Pivaloylindoles with Organic Azides

Ir(III)-catalyzed regioselective directC-7amidation of indoles in reaction with organic azides has been developed. While its efficiency was varied by the choice of N-directing groups, N-pivaloylindoles were most effective in undergoing the desired amidation at roomtemperature over a broad range of substrates. The reaction was scalable, and deprotection of the chelation group was also facile.

C7-sulfonamidation of indoles with sulfonyl azides is described. The developed method has good compatibility with diverse functional groups, providing various 7-amino-substituted indoles with good to excellent yields in a short time under mild reaction conditions. The key feature of the developed method is the regioselective functionalization at the C7-position of 2,3-unsubstituted indoles. Biologically active

Hypervalent iodine(III) compounds containing iodine–nitrogen bonds are very attractive amination reagents in organic synthesis. Heteroaromatic (aryl)iodonium imidescontaining a iodine–nitrogen bond and a hypervalent iodine(III) atom were prepared from heteroarenes, bis(sulfon)imides and (diacetoxyiodo)arenes under mild conditions. These compounds were stable under air and in organic solvents, and
