Salvileucalin C synthesis

Hanfeng Ding and co-workers from Zhejiang University have reported in Organic Letters on the synthesis of salvileucalin C. I thought of Sarah Reisman’s work but she of course made salvileucalin B. By the way, I noticed that Sarah Reisman was promoted directly from assistant prof to prof at Caltech so kudos to her.
