Development of a gold-catalyzed tandem reaction of 1,7-diynes with both internal and external nucleophiles was realized, which constructed five chemical bonds, two rings, and two stereogenic centers in a single step. Based on the novel cascade transformation, we achieved a unified strategy toward the stereoselective total syntheses of C-15 oxygenated drimane-type sesquiterpenoids and their analogues
实现了 1,7-二炔与内部和外部亲核试剂的金催化串联反应的开发,该反应一步构建了五个化学键、两个环和两个立体中心。基于新的级联转化,我们实现了对 C-15 含氧 drimane 型倍半萜类化合物及其类似物立体选择性全合成的统一策略,提供了天然产物 kuehneromycin A、antrocin、anhydromarasmone 和 marasmene 作为证明-概念研究。
