摘要
The steroidal natural product hippuristanol targets eukaryotic translation initiation factor (eIF)4A which plays a pivotal role in translation in eukaryotic cells. Now an efficient synthesis of hippuristanol from 11-ketotigogenin is reported. The synthesis features a rapid construction of a spiroketal unit via Hg(OTf)(2)-catalyzed oxidation/spiroketalization of the 3-alkyn-1,7-diol motif.
