Divergent Total Synthesis of Taiwaniaquinones A and F and Taiwaniaquinols B and D
摘要:
A divergent approach was developed toward the total synthesis of taiwaniaquinoids. An advanced intermediate 5a with trans NB ring junction was concisely assembled by employing a Bi(OTf)(3)-catalyzed cationic cyclization and a Wolff-type ring contraction as key steps. This common intermediate was readily converted to racemic taiwaniaquinones A and F and taiwaniaquinols B and D, respectively.
