2-Acetyl(ethoxycarbonyl)methylene-1,3-dithietane and -dithiane (1) were condensed with various aldehydes or ketones to afford high yields of the corresponding substituted 2-(1-carboxy-2-oxo-3-butenylidene)-1,3-dithietanes and -dithianes 4, which upon heating decarboxylated smoothly to give the title compounds in high yield.
