Synthesis and Reactions of 6-Aryl- and 6-Styryl-3-cyano-4-methylthio-2H-pyran-2-ones

The reaction of various types of acetyl compounds with a ketene dithioacetal, methyl 2-cyano-3,3-bis(methylthio)acrylate, in the presence of potassium hydroxide gave the corresponding 6-aryl- and 6-styryl-3-cyano-4-methylthio-2H-pyran-2-one derivatives.Th
