from 3-bromooxindoles was reported. This methodology leads to the efficient construction of a series of enantioenriched 3,3′-disubstituted oxindoles bearing vicinal all-carbon quaternary stereocenters via a dearomatization process of phenols under mild reaction conditions. Additionally, the representative large-scale reactions and related transformations of the dearomatized products reveal the potential
