A photoinduced electron transfer (PET)-triggered cascade reaction has been devised for the conversion of second-generation enol silyl ethers into angularly fused tricyclic scaffolds. Utilizing readily available and cost-effective DCA and phenanthrene as the catalytic systems, this cascade transformation is achieved with high efficiency. The reaction demonstrates a good substrate scope and excellent
设计了光诱导电子转移(PET)触发的级联反应,用于将第二代烯醇甲硅烷基醚转化为有角稠合的三环支架。利用容易获得且具有成本效益的 DCA 和菲作为催化系统,可以高效地实现这种级联转化。该反应表现出良好的底物范围和优异的立体选择性,从而丰富了PET诱导的级联反应领域。此外,通过该过程产生的自由基加合物可以作为合成复杂分子的有价值的亚基。
