Abstract:

Resveratrol-based natural products have received considerable attention as synthetic targets due to their versatile bioactivities and unique structures. Herein, we disclose our efforts toward the syntheses of polynapstilbenes A and B, which possess[C8-O-C-C-C7]-type dihydrobenzofuran skeleton that is distinctive compared with the other reported resveratrol-derived natural products. Our approach, featuring an acid-catalyzed conjugate addition followed by cyclization of para-quinone methides and phenols, affords two advanced intermediates that represents the dimethyl-protected aglycon of polynapstilbenes A and B.

Key words: Resveratrol, Polynapstilbenes A and B, Dihydrobenzofuran
