Detailed in this communication is an efficient synthetic approach towards the guttiferone family of natural products. Oxidatively unraveling a para-quinone monoketal followed by consecutive 5-exo radical cyclizations provides the bicyclic core. An additional strength of this approach is a late stage asymmetric desymmetrization of an advanced symmetric intermediate.
本通讯中详细介绍了一种针对天然产物古蒂法酮家族的有效合成方法。氧化解开对醌单缩酮,然后连续的 5-exo 自由基环化提供双环核心。这种方法的另一个优势是高级对称中间体的后期非对称去对称化。
