Ketene-S,N-acetals reacted with isothiocyanates to give β-aminothiocarbonyl-α-methylthioenamines, which were transformed into enaminonitriles by carbon-carbon bond formation with malononitriles.Treatment of the enaminonitriles with base afforded pyridine-

Lactam acetals (1-3) react readily with aryl isothiocyanates to form 1,3-diaryl-2,4-dithioxo-N-alkyl-azacycloalkanopyrimidines (6-11).With aryl isocyanates the products formed are dependent upon the ring size of the lactam acetal: 1-methyl-2,2-dime
