Chemistry of Heterocyclic Compounds Aims and scope

Abstract

By reaction of lactim ethers with N-substituted cyanoacetamides, the corresponding enaminoamides were obtained, cyclization of which by dimethylformamide acetal gave derivatives of pyrrolo[3,2-c]pyridine, 1,6-naphthyridine, and pyrido[4,3-b]azepine, having a substituent at the nitrogen atom of the pyridone ring. N-substituted furo[3,2-c]pyridines were synthesized from the diethyl acetals of butyrolactone and 3-(dimethylaminomethylene)butyrolactone and dimethylformamide acetal.
