A phosphine-catalyzed γ/γ-addition of oxindoles with allenoates has been developed that enables the efficientsynthesis of highly functionalized symmetrical 3,3-disubstituted oxindoles. This protocol features mild reaction conditions and wide functional group tolerance and affording corresponding addition products in good to excellent yields. Besides, we have also investigated the biological utility
