transformation of α-isopropylidene ketones into furan rings following a biomimetic approach. This methodology has been used for the synthesis of terpene furans such as mintfurane, curzerene, atractylon, and isoatractylon, all of them possessing interesting biological activities. The synthesis of linderazulene directly from 4,5-epoxygermacrone via a cascade reaction shows the potential of this protocol
系统I 2 /二甲基亚砜在仿生方法的作用下,将α-异亚丙基酮一步转化为呋喃环。该方法已用于合成萜烯呋喃,例如薄荷呋喃,姜油烯,白术和异白术,它们都具有有趣的生物学活性。通过级联反应直接从4,5-环氧germacrone合成linderazulene显示了该协议的潜力。另外,证明该化合物显示出显着的杀螨活性。
