Abstract Acetyl-substituted heterocyclic enamines 4 were synthesized from lactim ethers 2 and acetylacetone through condensation and deacetylation reactions, and they, along with the ester-substituted heterocyclic enamines 6, reacted with diethyl azodicarboxylate to afford C-adducts 7 and 8 in excellent yields.
