By reaction of lactim ethers with N-substituted cyanoacetamides, the corresponding enaminoamides were obtained, cyclization of which by dimethylformamide acetal gave derivatives of pyrrolopyridine, 1,6-naphthyridine, and pyridoazepine, having a substituent at the nitrogen atom of the pyridone ring.N-substituted furopyridines were synthesized from the diethyl acetals of butyrolactone and 3-(dimethylaminomethylene)butyrolactone and dimethylformamide acetal.
