Synthesis of Macrocyclic Lactams from Ketones by Ring Enlargement Reaction 2‐Nitroalkanon 1 was converted to the N ‐substituted amide 3 by condensation with acrylaldehyde followed by reductive amination. Under the analogous reaction conditions, 2‐nitrocyclododecanon ( 4 ) led to 12‐nitro‐15‐pentadecanlactam ( 6 ).
