The first total 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.
首次合成二芳基庚烷天然产物(2 R,4 S,6 R)-2-(4-羟基苯乙基)-6-(4-羟基苯基)四氢-2 H-吡喃-4-醇(4)和(3 R,5 R)-1,7-双(4-羟苯基)庚烷-3,5-二醇(12)是通过底物选择性氢化,四氢吡喃环的环裂解和Keck-Maruoka烯丙基化作为关键合成步骤而完成的。
