A new procedure for the synthesis of 12-oxo-1,15-pentadecanlactam (4) is described. Michael addition of α-nitro cyclododecanone to acrylonitrile followed by selective reduction of nitrile group of 2 gave the ring enlargement product 3, which was easily converted to 4 through Nef reaction. The total yield was 28%.

Key words: Michael addition, ring enlargement, Nef reaction, 12-oxo-1,15-pentadecanlactam
