Functionalized2,3-dihydro-1,3-thiazin-4 (1 H)-one derivatives have been synthesized by cyclo-condensation of 3-alkyl(aryl)amino-2-cyano-3-mercaptoacrylamides with aldehydes and ketones under acidic catalysis. 6-Alkyl(aryl)amino-5-cyano-2,3-dihydro- 1, 3-thiazin-4 (1H)-ones, when treated with a dilute solution of potassium hydroxide, are converted into the potassium salts of isomeric compounds, 1-alkyl(aryl)-5-cyano-6-mercapto-2,3-dihydropyrimidin-4(1H)-ones. Alkylation of the latter with dimethyl sulfate in situ furnishes 1-alkyl(aryl)-6-alkylthio-5cyano-2,3-dihydropyrimidin-4(1H)-ones, whereas boiling them in ethanol with an excess of hydrochloric acid leads to starting 2,3-dihydro-1,3-thiazin-4(1H)ones.
