12-Oxotetradecano-14-lactam was synthesized in 32% total yield starting from 2-nitrocyclododecanone by Michael addition to acrylamide, followed by Hofmann rearrangement and ring expansion, and Nef reaction. The conditions for the Michael addition of 2-nitrocyclodecanone to acrylamide, Hofmann rearrangement of the addition product, and the ring-expansion reaction were studied. The structures of the target compounds, intermediates, and byproducts were characterized by 1H NMR, 13C NMR, and infrared spectroscopic methods, mass spectrometry, and elemental analysis.
