for the construction of bridged tricyclic compounds with up to three quaternary centers, which are suitable for the synthesis of challenging bioactive natural products. For instance, the synthetic utility of this transformation is illustrated through a concise asymmetric total synthesis of the sesquiterpene (+)-zizaene in ten steps from a commercially available starting material.
描述了与 1,4- 和 1,5- 跳过二烯连接的亚烷基环丙烷 (ACP) 的分子内铑催化 [(3+2+2)] 碳环化反应的发展。这种转变为构建具有多达三个四级中心的桥联三环化合物提供了一种新方法,适用于合成具有挑战性的生物活性天然产物。例如,通过从市售起始材料分十步进行倍半萜烯 (+)-zizaene 的简明不对称全合成,说明了这种转化的合成效用。
