Abstract
The conditions of heteropolar and radical thiylation of 2-formyl-2,5-diethoxy-2,3-dihydro-γ-pyrans were studied. Oxidation of the carbonyl group occurs along with the Cannizzaro reaction in the reaction of 2-formyl-2,5-diethoxy-2,3-dihydro-γ-pyran with silver oxide in alkaline media. Oxidation of 2-formyl-2,5-dibutylthio-2,3-dihydro-γ-pyran with silver oxide leads to stable 2,5-dibutylthio-2,3-dihydro-γ-pyran-2-carboxylic acid.
