The firsttotal syntheses of diarylheptanoid natural products (2R,4S,6R)-2-(4-hydroxyphenethyl)-6-(4-hydroxyphenyl) tetrahydro-2H-pyran-4-ol (4) and (3R,5R)-1,7-bis (4-hydroxyphenyl)heptane-3,5-diol (12) were accomplished using substrate selective hydrogenation, ring cleavage of tetrahydropyran ring, and Keck–Maruoka allylation as the key synthetic steps.
