Appel reaction conditions have been harnessed to affect a mild biosynthetically inspired dehydration of endoperoxides to deliver multi-substituted electron rich furans. Unlike traditional dehydrative procedures, this method is metal and acid free, and can be achieved under redox neutral conditions. It is general for a range of aryl and alkyl substituted endoperoxides, and is functional group tolerant
利用了Appel反应条件来影响内合成过氧化物的温和生物合成激发的脱水作用,以递送多取代的富电子呋喃。与传统的脱水程序不同,此方法不含金属和酸,可以在氧化还原中性条件下实现。通常适用于一定范围的芳基和烷基取代的内过氧化物,并且对官能团具有耐受性。此外,该程序已用于提供呋喃脂肪酸(FFA)F 5的有效全合成。
