Rapid access to oxindoles by the combined use of an Ugi four-component reaction and a microwave-assisted intramolecular Buchwald-Hartwig amidation reaction
A two-step sequence involving an Ugi four-component reaction (Ugi-4CR) and a palladium-catalyzed intramol. amidation of aryl iodide has been developed for rapid access to functionalized oxindoles, e.g., I. Microwave heating was used to accelerate and to improve the efficiency of the intramol. Buchwald-Hartwig reaction. [on SciFinder (R)]
