A general strategy for the synthesis of tetrahydroquinolines and 1,4‐benzoxazepines has been developed via palladium‐catalyzed [4+2] and [5+2] annulations of propargyl carbonates with malonate‐tethered anilines and 2‐aminobenzylic alcohols. A series of six‐ and seven‐membered heterocycles with potential bioactivities was obtained in good to excellent yields.
