The reaction of derivatives of alkylidene(cycloalkylidene)cyanoacetic ester, -malonodinitrile , and -cyanoacetamide with dimethylformamide diethylacetal with subsequent cyclization of the resulting enamine systems gives derivatives of pyridine, 2-pyridine, and isoquinoline. 2-Amino-3-cyano-4-methylpyridine, which was synthesized by this method, was converted to a pyridopyrimidine derivative.
ACETALS OF LACTAMS AND ACID AMIDES. 39. SYNTHESIS OF THREE-RING DERIVATIVES OF PYRIDOPYRIMIDINES ON THE BASIS OF THE REACTION OF DIMETHYLFORMAMIDE ACETAL WITH DICYANOMETHYLENECYCLOALKANES

The reaction of dicyanomethylenecyclopentane and -cyclohexane with dimethylformamide diethylacetal was used to synthesize dieneamino nitriles, from which isoquinoline and 2-pyridine derivatives were obtained by treatment with ammonia.The reaction of 3-ami
