摘要

通过钯催化的铃木偶联/赫克环化串联反应，在一锅内制备出了多种双环芳香烯（BAEs）及其衍生物。在新方案中，以几乎等摩尔比的底物获得了令人兴奋的预期产物。这是一种非常有用的合成亚芴基 BAE 的方法。通过串联反应，还制备出了相应的梯形共轭聚合物。

Synthesis of bistricyclic aromatic enes and related polycyclic systems via Pd-catalyzed tandem Suzuki coupling/Heck cyclization reaction

A variety of bistricyclic aromatic enes (BAEs) and its derivatives have been prepared via the palladium-catalyzed Suzuki coupling/Heck cyclization tandem reaction in one pot. In the new proposal the expected products were obtained in exciting yields at nearly equimolar ratios of the substrates. It is very useful method for the synthesis of the fluorenylidene-based BAEs. Even the corresponding ladder-type conjugated polymer was also prepared by the tandem reaction.
