Abstract

Stemodan-13α,17-diol is a natural stemodane-type diterpenoid isolated from Stemodia chilensis. Herein we report the total synthesis of its epimer, stemodan-13β,17-diol, by applying titanium-mediated polyene cyclization and iron-catalyzed [5 + 2] cycloaddition as the key transformations to expeditiously install the molecular scaffold.
