Abstract
Described herein is a copper-catalyzed efficient oxidative dearomatized functionalization of indoles by using alcohols as the nucleophiles. Various 3-alkoxy-2-oxindoles were accessible with good isolated yields. The synthetic potential applications are demonstrated by the large-scale reaction, as well as the derivatization of the desired 3-alkoxy substituted-2-oxindole products.
