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.
为了快速获得官能化的吲哚(1),已经开发了一个两步序列,涉及一个Ugi四组分反应(Ugi-4CR)和一个钯催化的芳基碘分子内酰胺化反应。微波加热被用来加速和提高分子内布赫瓦尔德-哈特维格反应的效率。
