A divergent synthesis of functionalized unsaturated δ-lactones from α-alkenoyl-α-carboxyl ketene dithioacetals

(Chemical Equation Presented) A divergent synthesis of functionalized unsaturated δ-lactones 2, 3, 4, and 5 has been developed starting from the readily available α-alkenoyl-α-carboxyl ketene dithioacetals 1 in high to excellent yields under mild reaction

A novel route to alkenoyl- and cinnamoylketene dithioacetals

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.
