The chiral synthesis of the immunosuppressive sesquiterpene, FR65814 1 is described. The cyclohexane ring in 1 was prepared in an optically active form from D-glucose using Ferrier's carbocyclization reaction, and the carbon side-chain in 1 was stereoselectively introduced via chirality transfer by way of Claisen rearrangement of the cyclohexenol derivative, followed by Pd-catalyzed Stille coupling
描述了免疫抑制倍半萜FR65814 1的手性合成。使用Ferrier的碳环化反应,由D-葡萄糖以旋光形式制备1中的环己烷环,并通过手性转移通过环己烯醇衍生物的Claisen重排立体选择性地引入1中的碳侧链,然后进行Pd催化斯蒂尔耦合。双环氧功能是通过硫叶立德化学和钒催化的高烯丙基醇衍生物的环氧化立体选择性地构建的。第一次总合成完全证实了FR65814的拟议绝对结构。
