| Abstract: | Reactions of aromatic aldehydes with cyanothioacetamide and dimethyl malonate in the presence ofN-methylmorpholine affordedN-methylmorpholinium 4-aryl-5-cyano-3-methoxycarbonyl-2-oxo-1,2,3,4-tetrahydropyridine-6-thiolates. The latter were used to
synthesize substituted 6-(alkylthio)-2-oxo-1,2,3,4-tetrahydropyridines.
