  A Lewis acid-catalyzed tandem reaction strategy for the construction of a dihydrophenalene–lactone tetracyclic skeleton has been disclosed. Starting with 2-naphthol-tethered ketones and active methylene esters, the tandem reaction catalyzed by Sc(OTf)3 proceeded well to afford an array of dihydrophenalene-fused lactones with moderate to high efficiency and diastereoselectivity. Moreover, the synthetic

  已经公开了用于构建二氢苯那烯-内酯四环骨架的路易斯酸催化串联反应策略。从2-萘酚系酮和活性亚甲基酯开始，Sc(OTf) 3催化的串联反应进展顺利，得到一系列具有中等到高效率和非对映选择性的二氢苯那稠合内酯。此外，该方案的合成实用性通过简单的克级制备和多样化的产品转化得到了证明。
