The first total synthesis of racemic corymbolone, an eudesmane sesquiterpene isolated from Cyperus species used in traditional medicine to treat many diseases, is reported. In the developed sequence, the immediate precursor of corymbolone is the diol β-corymbolol, an epimer at C1 of the natural α-corymbolol. Thus, starting from the readily available Wieland–Miescher Ketone, the title compounds were
据报道,外消旋Corymbolone是从香蒲属植物中分离得到的一种大叶倍半萜烯,它是传统药物中的首个全合成药物,可用于治疗多种疾病。在已开发的序列中,Corymbolone的直接前体是二醇β-Corymbolol,它是天然α-Corymbolol在C 1处的差向异构体。因此,从现成的Wieland-Miescher Ketone开始,标题化合物分别在大约11和12个步骤中获得。总产率为3%。
