Abstract
- [Reaction: see text] O-Propargyl glycolaldehyde dithioacetals undergo a unique cyclization-rearrangement in the presence of mercuric chloride and calcium carbonate to afford 3-pyranones exclusively or along with 2,5-dihydrofuran-3-carboxaldehydes via their dithioketals and dithioacetals.
