Abstract

We report a modular synthetic approach toward the total synthesis of (+)-aureol based on a bioinspired gold(I)-catalyzed enyne cascade cyclization reaction. First, we investigated an array of catalysts to promote a 6-endo-dig cyclization of a highly advanced enediyne precursor. Since these studies result exclusively in the formation of the 5-exo-dig product, we synthesized and investigated a dienyne cyclization precursor in order to form the benzo[d]xanthene skeleton in a stepwise fashion.
