Synthesis of novel 7-substituted 5,6-dihydroindol-2-ones via a Suzuki–Miyaura cross-coupling strategy

A versatile method for the synthesis of new 7-substituted 5,6-dihydroindol-2-ones is described. The synthetic strategy proceeds through the use of the established palladium-catalyzed Suzuki–Miyaura cross-coupling reaction of halogenated indol-2-ones and arylboronic acids/esters.
