摘要

含有三环桥头堡碳中心的化合物是药物发现中的优势结构。在这项工作中，含有该亚结构的两种不同的多环支架已经通过不同的金催化的o-环丙基甲基-o ' -炔基二芳基的环异构化得到。对一种或另一种支架的选择性主要由温度控制。炔上芳烃基团的电子性质也起着重要的作用，这是根据所提出的机理来解释的。

Divergent synthesis of two polycyclic frameworks containing tricyclic bridgehead carbon centers by gold-catalyzed cycloisomerization of o-cyclopropylidenemethyl-o′-alkynylbiaryls

Compounds containing tricyclic bridgehead carbon centers are privileged structures in drug discovery. In this work, two different polycyclic scaffolds containing this substructure have been accessed by divergent gold-catalyzed cycloisomerizations of o-cyclopropylidenemethyl-o′-alkynylbiaryls. Selectivity towards one or the other scaffold is mainly controlled by temperature. The electronic nature of the arene group at the alkyne also plays a significant role, which is explained based on the proposed mechanism.
