Herein, we report the first intramolecular C–N bond formation of phenylpropanamide derivatives via organocatalytic oxidative reactions, affording 3,3-disubstituted oxindole derivatives with up to 99% yield. The high efficiency of this reaction is exemplified by the transition metal-free mild conditions and the ability to perform the reaction on a gram scale. Meanwhile, the DFT calculation of the catalytic
The Pd(II)-catalyzedC–Hbond activation/C–Nbond cleavage annulation reaction of N-alkyoxyamide aryne is developed to synthesize 9,10-dihydrophenanthrenone derivatives. This reaction exhibited good functional group compatibility with yields up to 92%. Detailed mechanistic studies showed that the key to C–Nbond cleavage is the formed eight-membered palladacycle intermediate undergoing nucleophilic
