title: Rapid access to oxindoles by the combined use of an Ugi four-component reaction and a microwave-assisted intramolecular Buchwald-Hartwig amidation reaction.
abstract: A two-step sequence involving an Ugi four-component reaction (Ugi-4CR) and a palladium-catalyzed intramolecular amidation of aryl iodide has been developed for rapid access to functionalized oxindole (1). Microwave heating was used to accelerate and to improve the efficiency of the intramolecular Buchwald-Hartwig reaction.
