Reaction of α,β-Unsaturated Carbodiimides with Enamines Leading to Fused Pyridine Derivatives

The treatment of (5,5-dimethyl-3-oxo-1-cyclohexenyl)iminotriphenylphosphorane (2) with phenyl isocyanate (3a) gave N-(5,5-dimethyl-3-oxo-1-cyclohexenyl)-N'-phenylcarbodiimide (4a) in situ.The reaction of 4a with enamines proceeded smoothly to afford the p
