Palladium‐Catalyzed [4+2] and [5+2] Annulation for the Synthesis of Tetrahydroquinolines and 1,4‐Benzoxazepines

Palladium‐catalyzed [4+2] and [5+2] annulations of propargyl carbonates with malonate‐tethered anilines and 2‐aminobenzylic alcohols were developed, giving the corresponding tetrahydroquinolines and 1,4‐benzoxazepines, respectively, in good to excellent yields.
