Shi, Hang published the artcileTotal Syntheses of Drimane-Type Sesquiterpenoids Enabled by a Gold-Catalyzed Tandem Reaction, Safety of (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Journal of the American Chemical Society (2011), 133(38), 14944-14947, database is CAplus and MEDLINE.
Development of a gold-catalyzed tandem reaction of 1,7-diynes with both internal and external nucleophiles was realized, which constructed five chem. 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 analogs, which provided the natural products kuehneromycin A, antrocin, anhydromarasmone, and marasmene as a proof-of-concept study.
