Abstract Asymmetric total syntheses of diospongin B and parvistones D and E are reported. Our strategy features a high-yielding three-step reaction sequence: Achmatowicz rearrangement, reductive γ-deoxygenation, and Matsuda–Heck coupling to construct the rare and challenging trans-2-aryl-6-alkyltetrahydropyrans, which serve as common intermediates for the syntheses of diospongin B, and parvistones D
