Comprehensive Summary The first catalytic asymmetric total synthesis of (+)‐propolisbenzofuran B, enabled by a highly enantioselective rhodium‐catalyzed hydrogenation tetrasubstituted olefin, was described. Other noteworthy aspects include the construction central hydrodibenzo[ b , d ]furan core through sequence Zn(II)‐mediated regioselective benzofuran formation and Dieckmann condensation, as well C‐H oxidations, involving visible light‐induced Fe(III)‐catalyzed benzylic C(sp 3 )‐H oxidation. Additionally, absolute configuration confirmed X‐ray analysis carbonate intermediate.
