Synthesis of acetyl-substituted heterocyclic enamines and their reaction with diethyl azodicarboxylate

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.

DECARBOXYLATION OF CYCLIC β-ENAMINOKETOESTERS WITH BORIC ACID

Cyclic β-enaminoketoesters prepared by condensation between lactim ethers and β-ketoesters are decarboxylated without deacylation by thermolysis in presence of boric acid to lead stereospecifically to cyclic β-enaminones.
