compounds (−)‐crinipellin A and (−)‐crinipellin B are described. The key advanced intermediate, a fully functionalized tetraquinane core, was constructed by a novel thiourea/palladium‐catalyzed Pauson–Khand reaction. This intermediate can serve as a common intermediate for the collective total synthesis of other members of the crinipellin family.
描述了自然有效的有效抗生素化合物(-)-crinipellin A和(-)-crinipellin B的有效总合成。关键的高级中间体,一个完全功能化的四喹烷核,是由一种新型的硫脲/钯催化的Pauson-Khand反应构建的。该中间体可以用作crinipellin家族其他成员的集体全合成的通用中间体。
