1‐Benzyl‐tetrahydro‐2‐benzazepin‐3‐ones 4 were prepared by submitting the corresponding 1‐benzyl‐β‐tetralones 3 to the Schmidt reaction. On the other hand, the rearrangement of the tetralones 3 by the Beckmann procedure gave 1‐benzyl‐tetrahydro‐3‐benzazepin‐2‐ones 5 . The syntheses of some hexahydrophenanthro‐azepines of types 10 and 15 are also described.
