An intramolecular hydroamidation of ortho-vinyl benzamides had been developed. The reaction was promoted efficiently by potassium tert-butoxide and N,N-dimethylformamide without the need for strong oxidants or transition-metal catalysts. A series of dihydroisoquinolinones and 3-benzylisoindolinones were prepared in good to excellent yields. The new method is operationally simple, scalable, and tolerant
