cis-fused and the five- and three-membered rings are mutually trans, provides a synthetic challenge for organic chemists. In this work, we took advantage of the photoinduced decarbonylative rearrangement of bicyclo[2.2.2]octenone to develop a new methodology for construction of the highly functionalized fused-5,6,3-tricyclic ring structure in a concise reaction sequence.
可以在多种具有有趣生物活性的天然产物的骨架中发现马拉曼倍半萜类化合物的结构。独特的稠合5,6,3-三环结构,其中的环是顺式稠合的,而五元和三元环是相互反式的,这为有机化学家提出了一个合成难题。在这项工作中,我们利用双环[2.2.2]辛烯酮的光诱导脱羰基重排,开发了一种在简洁的反应序列中构建高度官能化的稠合5,6,3-三环结构的新方法。
