Abstract
The asymmetric synthesis of three natural products: (+)-conocarpan, both (+)- and (–)- obtusafuran is disclosed. The highlights of the synthesis are the enantioselective hydrogenation of prochiral ketones via dynamic kinetic resolution to afford chiral alcohols. Intramolecular ring closure via either S<sub>N</sub>Ar reaction or metal-catalyzed C–O bond formation led to the construction of the <i>trans</i>-dihydrobenzofuran core.
