Abstract
A range of α-oxo ketene dithioacetals 1 reacted with Vilsmeier reagent (POCl3/DMF) to afford α-chlorovinyl ketene dithioacetals 2. With the treatment of NaOH in ethanol or methanol, the compounds 2 were transformed into the corresponding α-ethynyl ketene dithioacetals 3 in moderate to high yields.
Key words
alkyne - α-ethynyl ketene dithioacetal - α-chlorovinyl ketene dithioacetal - α-oxo ketene dithioacetal - Vilsmeier-Haack reaction
