approach for introduction of C-1 hydroxy on decalin ring system starting from (−)-carvone. Utilizing the substrate controlled Mukaiyama aldol reaction and alkaline cyclization as key steps, the C-1 oxygenated decalin eudesmane skeleton 2′ and its four isomers were synthesized efficiently. What's more, X-ray structural analysis confirmed sufficiently that something was wrong about the structure of natural
本文介绍了一种从(-)-香芹酮开始在十氢化萘环系统上引入C-1羟基的新方法。以底物控制的Mukaiyama醛醇缩合反应和碱环化为关键步骤,有效合成了C-1氧化的十氢萘烷骨架2 '及其四个异构体。此外,X射线结构分析充分证实了天然产物的结构有问题:文献报道了1β,6β-dihydroxy-7- epi -eudesm-3-ene。
