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 diethylazodicarboxylate to afford C-adducts 7 and 8 in excellent yields.

A systematic study of reaction of heterocyclic enamines with electrophilic alkynes: a simple and efficient synthetic route to 2-pyridinone-fused heterocycles
The reaction of heterocyclic enamines with ethyl propiolate and diethyl acetylenedicarboxylate has been systematically studied. In contrast to their heterocyclic ketene aminal analogues, heterocyclic enamines reacted with electrophilic alkynes via the Michael addition pathway rather than the aza-ene reaction mechanism. In the presence of a strong base such as sodium ethoxide and sodium hydride, the
