Abstract
When the solutions of methyl and ethyl esters of 4-oxo-3-phenylthioalkanoic acids are boiled in toluene in the presence of p-toluene sulfonic acid, substituted 4-phenylthio-2(5H)-furanones are formed in good yields. In the reaction with diisobutylaluminum hydride or organomagnesium compounds, the latter convert into the corresponding 3-phenylthiofurans.
