Abstract
Various 4-methylsulfanyl-6-pyridyl-2H-pyran-2-one derivatives were synthesized by the reaction of ketene dithioacetals with active methyl or methylene compounds in the presence of powdered sodium hydroxide in dimethyl sulfoxide (DMSO). Among these 2-pyrone derivatives, 3-aryl-4-methylsulfanyl-6-pyrid-2-yl-2H-pyran-2-ones show strong fluorescence in the solid state.
