5-disubstituted dihydrofurans. Hydrolysis of electrooxidation products with ion enchange-resin, followed by the treatment with base gave rethrolones. Furthermore, this method was applicable for the synthesis of 2-alkyl-4-hydroxycyclopentenone.
仅从 2,5-二取代
呋喃中就可以以良好的收率制备各种 Rethrolone。2,5-二取代二氢
呋喃的电氧化得到2,5-二甲氧基-2,5-二取代二氢
呋喃。用离子交换
树脂水解电氧化产物,然后用碱处理得到rethrolone。此外,该方法适用于2-烷基-
4-羟基
环戊烯酮的合成。
