First Time

A highly efficient synthesis of structurally diverse ortho-acylphenol–diindolylmethane hybrids 3 using carboxylic acid-activated chromones as versatile synthetic building blocks is reported here for the first time, through 1,4-nucleophilic addition and followed by a decarboxylation and pyrone ring opening reaction process.

Selective Ring Opening

An iridium-catalyzed branch-selective ring-opening reaction of vinylcyclopropanes with indoles has been established, which afforded C3-allylindoles in generally good to excellent yields (up to 95%). Considering that no wastes were generated in the whole process and branch-selective ring-opening reaction of vinylcyclopropanes was rarely reported, this strategy not only can be regarded as a highly atom-economic approach for C3-allylindoles, but also will greatly enrich the chemistry of vinylcyclopropanes.
