N-methylimidazole as a promising catalyst for the Aza-Michael addition reaction of N-heterocycles

N-Methylimidazole has been shown to be a promising catalyst for aza-Michael reactions. Various N-heterocycles were introduced to alpha,beta-unsaturated carbonyl compounds employing N-methylimidazole (0.05 equiv) in a highly efficient, rapid and high yielding synthesis of N-heterocyclic derivatives.
