- 論文の詳細を見る
The base-catalyzed reaction of diketosulfides (RCOCH<SUB>2</SUB>)<SUB>2</SUB>S (R=phenyl, <I>p</I>-tolyl) with biacetyl or benzil have provided high yields of 2,5-diacyltetrahydrothiophene-3,4-diol derivatives rather than the expected 2,5-diacylthiophenes. The diols have been transformed cleanly into the corresponding 2,5-diacylthiophenes by treatment with thionyl chloride-pyridine. In contrast, the reaction of the diketo sulfide (R=<I>p</I>-tolyl) with phenylglyoxal afforded a 2,5-diacylthiophene directly in good yield.
