oxidative cyclization mediated by Mn(OAc)3. Dihydrofurans 6–10 were obtained in moderate to good yields starting from 1,1-disubstituted alkenes. Dihydrofurans 11–15 were synthesized in moderate yields and unexpected cyclopropanes 16–19 were obtained in low yields starting from 1,2-disubstituted alkenes. This protocol offers access to various dihydrofurans which could be tested for their antiparasitic
使用方便的微波辐射协议以良好的收率合成 β-酮砜 1-5。这些砜通过由 Mn(OAc)3 介导的自由基氧化环化与烯烃反应。从 1,1-二取代烯烃开始,以中等至良好的产率获得了二氢呋喃 6-10。二氢呋喃 11-15 以中等产率合成,而意想不到的环丙烷 16-19 从 1,2-二取代烯烃开始以低产率获得。该协议提供了对各种二氢呋喃的访问,这些二氢呋喃可以测试其抗寄生虫潜力。
